I'm a physician with 50 years of medical practice. These are some of the best, most lucid and powerful lectures you can watch and study. Kudos to you for such astute organization and presentation skills.
brw im a student in kenya studying medicine bt inshaalah when i graduate i will donate money coz u are the better than all my lecturers combined......thank u so much
As a nursing student taking Cell Bio and A&P- his instruction taught me in 1 hour what I failed to learn over several weeks!! AMAZING is an understatement!!! Thank you, Thank You, Thank you!!🙌
Alhamdulillahi Rabbil A'lamiin. This is one of the most elaborate and insightful yet summarized lessons I've ever had. You can't understand better than this! I look forward to attending more of this kind. Thank you.
I am studying medical school in Turkey and have lots of problems in understanding the lectures but your videos are helping me way too much please keep making videos and helping people all around the world. Thank you
Dear ninjas I wanted to express my appreciation and awe of your work. I'm a chiropractic science student, ex high school teacher, still working full time whilst i study part time and hitting it hard but your videos are so well done. You are born performers teachers scientists and thoroughly inspiring. i just wanted to validate your work. you are so great i'm so grateful for your youtube offerings. if being in contact with a british science student, living in Perth Australia, singing your praises to everyone she knows helps you, get in contact. otherwise i will keep supporting you, with the means I have and sharing the good news of your self actualization and awesomeness. Keep the faith Ninjas, you are appreciated world wide :) thankyou! Sacha Norsworthy
Don't know if you'll see this but I wanna say a huge THANK YOU to you and your team for all your efforts! I just submitted my assignment and I think it's best piece of work I have ever produced because of how amazing your videos are! Thank you!!! 🥰💖💖💖
hii! I’m a first year med student from Portugal. Older students recommended your videos and I can see why! You really are loved in my university. Thanks a lot for your content!
This is the best ever cell cycle class I had... Really I understood concept very well... I can relate you to one my school teacher, who always made her classes interesting...... You are inspiring me to explain all these concepts in Kannada ( my mother toungue - Karnataka, India).... So that many more students, especially the rural students will continue their studies in science stream... Here in India we the students who studies in local language medium will find it hard to study science, as in higher studies they have to suddenly switch to a English medium...when they switch to English medium they find it hard to understand every word and just opt to move away from science stream... ( even I faced such problems )... Hopefully I can help them in future...
Man, I couldnt understand Cell division videos of 10min because there were so many things that didnt make sense to me, but you always give an explanation to everything, so it all makes sense. Youre amazing at teaching!
I am a pharmacy student from Africa, i am in Near East University Norther Cyprus, i am speechless about your skills bro, you are the man, i can only compared your competence,skills and impeccability to that of a Cell that is small but does a wonderful job. the fire that was quenching in me has been fueled to burn again with your lectures. God bless and keeps you with abundant energy bro.
I have my first AnP exam tomorrow and I didn't understand anything the teacher taught,I have to study all the system,cells, sense organs etc,I was scare until now,I found you and I feel calm,I feel like I can pass this exam 🥰☺️
It's my first time that I am watching your lecture. I am super impressed of the way you teach and manage the lecture in a specific time. Thank you so much.
Your videos on the cell are so helpful and accurate. It amazes me how well you can talk freely about such complex topics with tons of specific vocabulary. I would have never been able to understand this so well if I had just used our recommended literature at Uni. Thank you!
I really don't think you understand the impact you have in this world lol you have changed the game of education for me since freshman year of college. I graduated last year and I'm currently studying for the MCAT and you have been my favorite resource. Thank you so much for all your effort :")
God bless you abundantly for this video. I have been encountering difficulties in understanding cell cycle, but your explanation has made it so easy to understand. God bless you once again sir.
I am inlove, I am obsessed with science >>> science is wonderful ❤❤ . Thank you ninja nerd , your explanations are brilliant.... big big fan from Namibia 🇳🇦
OMG I'm studying this for years and I still have no idea. But when you explain the concepts I'm starting to understand! Turns out it's quite easy😁. Keep up your good work, Professor! Thank you very much! Love from Indonesia 💟
"ain't that cool? Our body is amusing" I love how passionate you are about this 😭😭💕💕 it really inspires me in my mindset and attitude towards studying. God bless you
Hello NinjaNerd! I think I may have found a discrepancy in this video around 16:20. During the S phase you state that the cell becomes tetraploid (4n) - I believe the cell stays diploid but has 4C (twice the amount of genetic material) after replication.
During endoreduplication, the cell replicates its DNA without going through the usual process of mitosis. This results in a tetraploid cell with four sets of chromosomes. During anaphase. In mitosis DNA content is doubled during S phase resulting in 2n chromosomes having two chromatids so, yea
I was feeling unmotivated to get prepared for this semester... As soon as I watch your videos I feel so motivated and excited! I recommend you to all my nursing friends.
Bro, I just love your explanation process.. all my questions about the topic is solved after watching your video.. Thank you and love you from Bangladesh..
Thank you, thank you!! You are an amazing teacher and my go to when I need to really understand what they want to test me on. Teachers don't seam to teach much anymore and I need this type of hands on teaching. And I am a highlighting, drawing and connecting type of learner so I absolutely LOVE all the colors you use and especially love the sound of the marker caps clicking louder when you get excited about a topic. It makes it much easier and fun to learn!! Thanks again for helping me get As 😍
dude are you real? like i am so happy i finally found a complete long lecture about the topic that isnt 10 min or too animated but shallow content-wise, i mean you are incredible! thank you so much for focusing on depth over crazy animations, shortness or fun facts, just old fashion in depth well structured lecturing is sometimes essential and thank you for meeting that need for free.
God has blessed you with a gift of excellent teaching skill. We like the way you make the topic simple and easy to understand. I request you to make a video on the topic "Meiosis".
I've been just watching hours of your videos. If I want to get more in depth than "crash course" this is where I go. You've helped me feel a little better about my bio final since I can't use notes and an AI will be watching me to make sure lol. Thanks again!
I'm a master student in cell Biology and your classes are essential to me to understand my project background! Thanks a lot! Keep going with the great work!
i am a physician and i thought your cell cycle lecture was more then outstanding !!!! i keep watch your incredible performance and enjoying more then a movie !!!! dr Katherine Reese Er doctor
"Why are these things happening?" Because God gave you much wisdom & enthusiasm in science, purely and simply to help people like me with ADHD who need visual audio kinetic reinforcement. Truly, God bless!
Did god also make the babies with anencephaly? Go ahead, google the condition and tell us how wonderful your alleged invisible, eternal, immortal sky wizard is.
I have always faced prblm learning this topic... but today it was all clear and so simple... I'm glad I choose to watch it here... thankyou for your hardwork... it was totally worth it... fit in my memory forever.... 👍
just to clarify about what Zach said at 15:55, chromosomes DO NOT double after DNA replication. before replication you have chromosomes consisting of 1 CHROMATID, which gets replicated forming 2 sister chromatids joined together via a centromere. you go from 46 chromatids to 92 chromatids, the chromosomes stay as 46.
brother, you are definitely doing a wonderful job but it will be so beneficial for me and other students if you could make more videos in terms of molecular biology. .....
I have a bio exam tomorrow and you have taught me more in this video then I have learned the whole time being in lecture, studying flashcards,and looking over my review. In other words thank you for keeping my GPA up and teaching in a way that helps this info stick in my brain.
Amazing teaching. Thank you for your great work and ad free videos. I'm happy to support you on patreon. Two things: - Personally, I'd move your support call up in your video description so that people can see it without having to click an extra time. - If I'm not mistaken though, you might have used the terminology of chromosomes and chromatids a bit unclearly. During the G1 phase, there are 46 chromosomes with 1 chromatid per chromosome (so 46 chromosomes AND 46 chromatids). And after the S phase, there are 46 chromosomes with 92 chromatids (not 92 chromosomes).
AMAZING! AFTER ALL THIS complexity, tuning, and order how any one can even dair to belive in eveluotion and say (we are sons of coincidence) WHER IS YOUR MIND PEPEOL!
Actually this is exactly what evolution is. A cell wouldn’t have become this complex without billions of years of evolution to reach what it is today. WHERE IS YOUR MIND!!
@@mohammedalharbi6474 : sorry my dear, but after high level of complex such like this, "billions of years" of random knocking at the genatic material doesn't make any sense to me 'neither siens Scientifically nor logically and I change you to prove this, put please bro I want siens and logic not strang stupid stories.
@@AhmedSalah-sr3os just because it doesn’t seem logical to you, doesn’t make it wrong. Evolution is real. It’s a fact with thousands of evidence and real life applications. You can do your research. Have a good day
@@mohammedalharbi6474 you know bro... this is the strang thing I guess,ther is no even one complete evidence for this eveluotion can you imagine! and by complete evidence I mean until now, we don't have a transitional animal fossil, and we can't intentionally create evolution in the lab despite our claim that it happened by chance, so how we can say "this is siens" ! all we have guesses of people say that they are scientists and even them, they are not sure! and you can do your search bro.
@@AhmedSalah-sr3os First, complexity is not the sign of a good designer, simplicity is. If you get 20 designers and give them a specification, and all 20 created designs that meet all criteria, the best designer is not the one with the most complex design, but the one with the simplest design. Second, it is a logical fallacy - straw man - to refer to evolution as random knocking at the genetic material. For example, you leave out natural selection, which imposes a directionality onto evolution by tending to eliminate deleterious mutations, and to retain - and spread - beneficial ones.
I attended many classes,watched many videos online but still didn't understand the whole cell cycle but now my concept are totally clear about cell cycle.Thank you🙏
We should call this process the lonely dance of a cell - a beautiful orchestration going on in there. Also kudos for the teaching style again - the great thing about these videos is that they are so easy to navigate through.
i dont think it goes from 2n to 4n in mitosis. it stays 46 chromosomes with a diploid number of 2n but it now has sister chromatids. so you have 92 total chromatids. number of chromosomes stays the same in mitosis.
@@noorbhatia1200 it's kinda funny he even talked about how the number of chromosome means the number of centromeres independently on the number of actual DNA copies but still made the very mistake
"number of chromosomes stays the same in mitosis." Not after the sister chromatids separate during anaphase and on into telophase, prior to cytokinesis. At that point, the cell is 4n.
I am supposed to be marking but I can't stop listening to you explain. I don't know if you have a team but great job! I am sure that there is so much being sparked beyond learning, imagining and being inspired in these students' minds through watching these videos. I'm so mad you hadn't created these while I was studying. Continue the good work. Your fellow Ninja Nerd xoxo
27:56 "friggin freak of nature" Awesome, just the kind of terminology that I understand In all seriousness thanks for making this so comprehensive and easy to grasp! You really are a ninja nerd!

Not after the sister chromatids separate during anaphase and on into telophase, prior to cytokinesis. At that point, the cell is 4n.
