The best part about his style of teaching is the storyline and narrative visuals. He doesn’t just point out and explain, he makes you UNDERSTAND the whole biological process regardless how abstract the concept is. He paints a picture that you will remember, and that in itself, is a true talent. 💯
I need his enthusiasm for my studies!!!! His passion for Medical Science is contagious and so his happiness while explaining concepts. How even the most complex of topics start appearing lucid. Such a kind soul... I owe him so much !!
I know this is an old video but I really want to say thanks. I'm literally going to cry omg I always hated biochemistry in my veterinary medicine studies but I finally got it and your video is so detailed yet so understandable. I searched forever to find videos that explain this topic/ Genetics and include all the information they test us on. Your channel is like a gift from god. Especially with the clinical references omg it's so helpful to connect the dots. I`m so happy, sitting in my room crying happy tears. I never knew biochemistry could be enjoyable but watching you explain everything is so much fun. Asking "me" questions and knowing the answers repeading the stuff by watching and being able to remember it omg you saved me. Lots of love from Germany
I was starting to doubt why i study biology because having to study off of 1000 page books was just miserable and made me feel stupid for not remembering a thing afterwards. Your videos have been extremely helpful making me understand and memorize the subject better! Thank you so much for reigniting my passion for science and reminding how interesting and cool molecular biology can be!!
You've saved me throughout my nursing school and now again during MCAT studying!!! WOW CAN'T SAY THANK YOU ENOUGH!!!! YOU AND YOUR TEAM ARE AWESOME HUMANSSSS!
This video is incredibly good. I'm a senior high school student from Spain, and I have my bio test next week. I've been looking for videos that explain the DNA replication properly and easily, and I hadn't found any in my language. But THIS ONE. Perfect explanation, super easy to understand every single step. Thank you so much Professor Murphy!
I'm a dentist. Passed my boards years ago and am fully licensed but... man, I feel like a student all over again! This is a phenomenal presentation and a great review! I hope you consider becoming a university professor one day. (I like studying USMLE material to make me a better overall provider - in case you may wonder why a dentist would be on this video).

I am a 70 year old woman. The kids are raised and I want to learn new things. I have had no college, just high school. I'm here because I have always had a curious mind. This is like therapy for me... stretch those brain cells! Love it!
Hi, I am a med school student and I hadn't been able to grasp the whole concept for my bioscience class until now. Just wanted to thank you for helping me prepare for my final exam which is coming soon!
This man is straight up inspiring... I'm currently a molecular biology major but I'm thinking of teaching for a year or 2 because I genuinely enjoy the passing on of my enthusiasm for this subject. I hope I can convey my knowledge to students in such a fun and followable format. Takes a special kind of mind to present complex topics in such a broken down, easy to follow, and enjoyable lesson. You really are talented!
1st year med student here and a big thank you for all the effort around embryology biochemistry and even in phisyology you are really making it easier and I am really thankful Much love and respect your nerd from egypt
God bless you dear Menna! I wish you only the very best with your studies. I carry many wonderful and fond memories, of beautiful and amazing Egypt. The Egyptian's were always very intelligent, not to mention, multiple languages must be fluently learnt @ school, before reaching a pass level. I graduated many moons ago now, but i still get excited, when i watch Medical Science lectures. It takes me right back, to where i once began my lifelong career. Take care, stay focused and stay positive. x

OH GOd, literally the best translation EVER, now it's so easy to understand and connect all of that information. It blows my mind that this is actually possible to understand and memorise.
Been super deep into your Neurology playlist these days. was watching your "Descending Tracts: Overview" right now. saw u uploaded this one. came here just to say thank you. words can't describe how much thankful i am.
This video is just amazing !!!! U explained a whole lecture taken in 4 hours in just an hour and so smoothly!! We can’t thank u enough and literally ur the one who is helping me pass my medical years !!! Thanks a lot !!
Hi ,I just want to thank you for all the lectures in science.I am a retired nurse and I have been reviewing and learning again by watching your videos.I always enjoy learning so I make watching your videos part of my daily schedule.I love the drawings and your passion in explaining the difficult parts.More power to you.
You have the ability to make things so simple and easy to grasp. All my years of schooling and professors and I still go to you when I need a concept broken down. Thank you.
This professor has NO IDEA I’m one of his students! I’m here for the unmatched enthusiasm! The drawings and great explanations. Can’t wait to take a test tomorrow. 🤣 Dunno how he makes it a whole hour without half times or time outs. 😊 thankful I can pause and re-play explanations over and over until I get it!
JUST WOW! I'm a clinical laboratory scientist and I’ve been struggling with biology since ever! before I find this channel, I find biology sooo hard to understand. now I even enjoying it! Thanks, Zach You’re a great teacher💯And this channel is incredible 🤩
I have been glued to absorbing your teaching. Thank you for providing the world with education. Your lectures are so clear that you kept my attention span. Where have you been all my life? I don't know if it's the passion radiating from the screen, the deep breaths you take before diving in, the multi colors on the whiteboard, your already prepared drawing, me following your lead when you sit down, or the fact that you stay on point. I appreciate this very much.
The dedication! The excellent diagrams! The personality!!! I am blown away that this is free THANK YOU from the bottom of my heart for helping me graduate
4 months of my biochemistry professors lectures vs a few hours of zachs videos, and I see a big difference in my learning. thank you Zach for making learning so easy. I've said it before and ill say it again if I die and you want my organs pls take them.
Thank you very much you have explained these complicated concepts in a clear and concise manner my college Biology Professors cannot explain in a million years. I feel a sense of relief when you explain scientific concepts. Thank you very much.
I have never seen anyone explaining like you You are simply extraordinary I don't have words to say how good your teaching is. The way how u make us understand the concept is amazing.
As a genetic engineering major I've been studying this particular subject as a core course part. Each year it progresses on to the more advanced aspects. I can vouch that this hour long video perfectly encapsulates 3 year long course progression. Well done.
Hello you are genetic engineer so please answer my doubt..11th student in India 1.number of dna in chromosome..2number of histones to wrap one dna.3how is centromere formed to attach 4.dna replicate..ok..but how it unwrap from histones..and what happens to histones
Dont know how to be thankful for u..your classes are very much helpfull for my pg exams.The way of teaching itself made the entire concept remind in the mind .and does not required any extra time for studying.your explanation made me to understand with complete process and does not requires any extra time for preparation.Like an artist paints a picture .for me your a gift from god.Thankyou so much sir for helping to complete my postgraduate so smoothly.🙏🙏 Love from India
You are a brilliant lector and teacher! Even with not advanced english I understand such a difficult material. All because of your talent. Thank you a lot for this work!
legit a lifesaver! I am studying for a final and could not find a video that explained this concept step by step! this was so helpful and he broke it up step by step! thank u so much!!
You are the GOAT bro. I also help students in A&P and physics and I have learned a lot from you and your "easy-to-comprehend" teaching style. I bought a shirt to bring you in some extra cash. I will buy many more in the future if you can do different materials! You help a lot of people, so thank you for all your hard work!
They don't pay high school teachers enough to attract this caliber of teacher. That's a rare bird that will teach high school when they have the background and ability to get much higher salaries in other places. (Which job would you choose when the salary is so vastly different).
The RUclips presentation can make money also and the person only has to make the presentation once . (plus no distractions from attention seeking young folks). lol
I absolutely love all these lectures, you are seriously the best teacher that I have ever had. I am in NP school and you are teaching me just about everything. I have developed a habit where I read the material watch your video over and over than go back and read again, and everything makes complete sense. Thank you sooooo much please never stop posting !!!!!!!!!!!!!!
Look, I want to thank you to the infinity; you have managed to make me love medicine with your fantastic explanations of things. You are a wonderful lecturer keep going and remember that there are many people who appreciate what you are doing. I'm a medical student by the way
I appreciate your videos! I get anxiety when I read the textbook and cannot understand what is going on. You really break everything down and have helped me tremendously! Taking an exam on membrane transport, DNA replication, and cell cycle this weekend! I feel confident 😊
I dont know how u garner such intricate understanding of all this. Biochem goes whoosh above my head! But you! You make things easy for my tiny brain! Thanks a lot. Really grateful!
As a physician, I am almost not clear about molecular, biology and things like that but since I have known your channel, submerging in your lectures, I was able to understand that challenge knowledge. Thanks very much for your dedication. Love from Vietnamese fan
Hi, Sir I've Some Questions 37:15 you said that helicase is unwinding the DNA to Both Directions Right and Left. Then Why we only need another primer on Lagging strand? We're also moving towards the left side with helicase and leading strand doesn't use primer why? Another question is in Termination. Where Telomerase enzyme comes and elongate the parental strand. I want to know that why we're elongating Old DNA Strand because the only strand that is shorter is the New Strand. And also after elongating where the RNA Strand of Telomerase will go?
Waaaaaah!!!! Finally FIIINAALLLYYY GENETICS! 🥺🥺🥺🥺🥺 I was waiting for this looong time ago...i am really happy and waiting for transcription, and translation 🙏🙏
I just wanted to put out this - there's like tons of people on youtube trying to explai things easy but when I look at my notebook its the same as always! just a mess! BUT! when I draw with Zack, it just makes sense! Thank you so much for all the helP!
I am a first-year pharmacist student and I currently read biochemistry, I hated it until I found you. My literature is in English but we have to learn everything in our native language. So the teacher lectures in Swedish. But they are so bad at explaining so I was close to quitting because I didn't understand anything. Even though you speak English, it is so much easier for me to understand you rather than my teachers. I am so grateful for these videos!
Currently mid video and I just had to stop and comment...WOW! My brain is on fire! Not only are you delivering content, but you're making it make sense in such a simple way. So happy I found your channel!!
I love love love love your videos, my friend. I have watched them and learned from them since my high school days. I am doing my Master's in Zoology currently, and I still watch your videos for a lot of my topics. You remind me why I love Biology and I hope you continue to post more. Great work.🥰🥰 I would love to meet you someday in person🤩🤩
i can't express how thankful i am to you Zach!! you're saving me your happiness while explaining is my happiness while understanding thank you so much 💖💖 sending love from Algeria I'll mention you in my graduation speech insh'allah!!
I know this is an old video but I wanted to put this in here and say that I am using this now within college genetics, and I find myself learning more from here than I cant from other videos thank you for what you do, and the visuals that you do because college professors will just assume we all know before class.
Regarding telomeres, presumably after telomerase has extended the parental lagging strand, the DNA polymerase will extend the incompletely finished daughter strand to match the extended parental strand. I was confused about that but otherwise great overview!
I've been a student of biological science for years. There's certain concepts that I don't readily remember because my education hasn't been continuous like most. Now as a student of bioinformatics, the importance of A-T-rich and C-G-rich regions is an important concept. Glad I had this reintroduced.
You are a true hero I really can’t thank u enough I don’t like biology but I’m a med student and i really started liking it thanks to your videos, your passion when u talk is truly inspiring
I cant believe that I pay over 30k a year to a university and I learn 100x better from you. You explain these topics so much better than any professor that I've had my entire time in college.
My friend and I are in dental school rn Year 1 and you word for word explained the whole half of one of our lectures but for some reason i feel like it just STUCk in my brain!! thank you!
Your videos really help me going over my old notes. (Apparently I suck at taking notes) Especially my Genetics notes were a total mess and your videos helped me understand what my notes meant. Thank you for your work.
Love the videos! I´ve been struggling to understand this theme, but after I have watched this video, It all made much more sense. Thank u for being so good at learning and you make biology actually fun and understandeable. Keep up the work! :)
the way you explain these concepts is making me be even more passionate about this field! thaaank you! I think most of the doctors of the next generations will have to thank you for eternity :)))))))))
wonderful explanation. you can get so many videos on DNA replication on youtube, but if you want to study it in very much detail without consuming too much time, this is the best video as he explains so well that you save a lot of time from understanding. It is as if even if you, have half the knowledge, you will be intrested in knowing the full mechanism of DNA replication
So grateful for you guys. you are unarguably amazing. if i ever get anywhere close to your level of knowledge, enthusiasm and sheer awesomeness i'll be grateful. carry on self actualising!!!
@@chaimabeens Maybe because the helicase is going to the right side and finsh all the DNA and you don't have any 3' becasue it is the end of the dna , while in the lift side you will have 3' because it is not the end of the DNA SORRY my english is bad, i hope you get it
I like your style, your way of teaching, and how you relate basic scientific facts and processes to medicine.Time literally flies when I am watching your videos!!!
No, the direction in leading strand is from 3_5 just the same direction of Helicase work so as the Helicase open strands the process will remain at same direction , which is the opposite of lagging strand
I really really enjoyed your lesson. I've always believed that teaching is an art and not everyone is good at it but you are clearly a master! thank you for making this series.
Hi thank you so much for this lecture! There is one thing I wanted to clarify, I hope I can ask about it here. So when you were talking about the leading and lagging strand I just wanted to clarify that the Okazaki fragments are in fact present in both top and bottom parental strand. Is this correct? What I understood from the video is that the leading strands are found in the top parental strand while lagging strands are found in the bottom parental strand as the synthesis occurs 5' to 3'. But the replication is bi-directional so this means Okazaki fragments must be present in both parental strands right? Am I correct in assuming that when you were talking about the leading and the lagging strands, you were just looking at one direction of replication for simplicity sake to explain the concept? I hope what I said makes sense. I just wanted to make sure my thought process isn't wrong. Thank you!
You're absolutely right, no strand is truly ONLY leading or lagging (except perhaps at the very end of a chromosome), this concept only holds true if we're looking at one replication fork or a replication bubble where one strand has a primer somewhere in the middle. Okazaki fragments occur on BOTH strands.
The best part about his style of teaching is the storyline and narrative visuals. He doesn’t just point out and explain, he makes you UNDERSTAND the whole biological process regardless how abstract the concept is. He paints a picture that you will remember, and that in itself, is a true talent. 💯
Ok

@@ItsGraceDiamond GOOD! I passed with a pretty good grade!
How many ATP is required to cut H- bond by DNA helicase?

i can't express how thankful i am to you Zach!! you're saving me
your happiness while explaining is my happiness while understanding
thank you so much 💖💖
sending love from Algeria
I'll mention you in my graduation speech insh'allah!!
You inspire me! I watched your videos and made me think about taking up masters. I’m a clinical laboratory scientist. Thank youu ❤️
I know this is an old video but I wanted to put this in here and say that I am using this now within college genetics, and I find myself learning more from here than I cant from other videos thank you for what you do, and the visuals that you do because college professors will just assume we all know before class.
Regarding telomeres, presumably after telomerase has extended the parental lagging strand, the DNA polymerase will extend the incompletely finished daughter strand to match the extended parental strand. I was confused about that but otherwise great overview!
I've been a student of biological science for years. There's certain concepts that I don't readily remember because my education hasn't been continuous like most. Now as a student of bioinformatics, the importance of A-T-rich and C-G-rich regions is an important concept. Glad I had this reintroduced.
You are a true hero I really can’t thank u enough I don’t like biology but I’m a med student and i really started liking it thanks to your videos, your passion when u talk is truly inspiring
It's really hard to find the right words to say, bcz thank you is really an understatement.
turning off ad blocker for your videos. massive props
Download teh video

I cant believe that I pay over 30k a year to a university and I learn 100x better from you. You explain these topics so much better than any professor that I've had my entire time in college.
I’ll become best doctor because of u man
My friend and I are in dental school rn Year 1 and you word for word explained the whole half of one of our lectures but for some reason i feel like it just STUCk in my brain!! thank you!
Gosh....1 hr lecture feels like three blinks of an eye.
Your videos really help me going over my old notes. (Apparently I suck at taking notes) Especially my Genetics notes were a total mess and your videos helped me understand what my notes meant. Thank you for your work.
Love the videos! I´ve been struggling to understand this theme, but after I have watched this video, It all made much more sense. Thank u for being so good at learning and you make biology actually fun and understandeable. Keep up the work! :)
the way you explain these concepts is making me be even more passionate about this field! thaaank you! I think most of the doctors of the next generations will have to thank you for eternity :)))))))))
This is cool and I am learning so much about cell biology thank you!
Is there anyone else who’s better than this Ninja ? I feel like a nerd now. Once I get my first job I will subscribe to be your patron. I love you
On spring break this week and start DNA next week.
wonderful explanation. you can get so many videos on DNA replication on youtube, but if you want to study it in very much detail without consuming too much time, this is the best video as he explains so well that you save a lot of time from understanding. It is as if even if you, have half the knowledge, you will be intrested in knowing the full mechanism of DNA replication
So grateful for you guys. you are unarguably amazing. if i ever get anywhere close to your level of knowledge, enthusiasm and sheer awesomeness i'll be grateful. carry on self actualising!!!
The way he smiles😄😄 and the way he proceeds in a story manner is just a magic 🎉
1:00:18 why this didn't happen in the leading strand there is also no 3 prime ends to add after we remove the primers ? or I am understanding wrong
9 months later & i have the same question as urs!!!
@@chaimabeens Maybe because the helicase is going to the right side and finsh all the DNA and you don't have any 3' becasue it is the end of the dna , while in the lift side you will have 3' because it is not the end of the DNA
SORRY my english is bad, i hope you get it
I like your style, your way of teaching, and how you relate basic scientific facts and processes to medicine.Time literally flies when I am watching your videos!!!
Thank you sir
I love love love this channel and WISH I had you as my biology teacher, maybe then I would actually understand and enjoy the subject
I do have a question : Doesn't Helicase work on both ends so wouldn't the leading strand will also have few nucleotides left like the lagging strand?
Yes that’s what I was also about to comment ☹️☹️☹️☹️
Same question
No, the direction in leading strand is from 3_5 just the same direction of Helicase work so as the Helicase open strands the process will remain at same direction , which is the opposite of lagging strand
I really really enjoyed your lesson. I've always believed that teaching is an art and not everyone is good at it but you are clearly a master! thank you for making this series.
Hi thank you so much for this lecture!
There is one thing I wanted to clarify, I hope I can ask about it here.
So when you were talking about the leading and lagging strand I just wanted to clarify that the Okazaki fragments are in fact present in both top and bottom parental strand. Is this correct?
What I understood from the video is that the leading strands are found in the top parental strand while lagging strands are found in the bottom parental strand as the synthesis occurs 5' to 3'.
But the replication is bi-directional so this means Okazaki fragments must be present in both parental strands right? Am I correct in assuming that when you were talking about the leading and the lagging strands, you were just looking at one direction of replication for simplicity sake to explain the concept?
I hope what I said makes sense. I just wanted to make sure my thought process isn't wrong.
Thank you!
You're absolutely right, no strand is truly ONLY leading or lagging (except perhaps at the very end of a chromosome), this concept only holds true if we're looking at one replication fork or a replication bubble where one strand has a primer somewhere in the middle. Okazaki fragments occur on BOTH strands.
This has been giving me hard time,but with this intelligent man,i will understand better the biochemistry
I will be buying your merchandise for real way better than watch slids
You are the best teacher ever♥️
