How are Proteins Made? - Transcription and Translation Explained #66
HTML-код
- Опубликовано: 14 мар 2020
- This video covers:
- The two steps of protein synthesis: transcription and translation
- Transcription is the production of mRNA, which is a copy of a gene
- Translation is the production of a sequence of amino acids (a polypeptide) using that mRNA

i spent 6 hours trying to understand this until i came across your video and you managed to explain it perfectly in the first 10 mins - the concept finally clicked in my mind THANK YOU SO MUCH!
same here
exactlyyyyy
Yessssssss
Sameeeeeee
Same here
thank you so much that's the least confusing and clearest explanation on protein synthesis I've ever seen
ive never been able to grasp onto protein synthesis for so long and i was super scared that it would bring down my grade in my upcoming exam, but ur vid made it super clear, like i genuinely got excited that i was finally able to understand the concept- thank you so much!! i honestly cant thank you enough
you are welcome
@@ss-hc7tb why are you saying that lmfao
same!!
we done found bro 😭🙏
@@Asilo. WHAT
THANK YOU THANK YOU THANK YOU!!!! You are so underrated that I can even describe it, this is lifesaver. The channel was recommended by a friend and I must say I’m grateful for finding it. Best of luck and stay safe you’re amazing
This was all so confusing for me and suddendly with a ten minute vid you made it so clear, so simple- Thank you so much! you explain really well
Im from Algeria and im about to pass bacaloreate exam this year inshallah and i understood that lesson much better after watching ur video. Thank u soo much
In Sha Allah**
InShaAllah (i hope u did)
I CANNOT THANK YOU ENOUGH, AMADEUS AND TOM!!! You are literally every student's savior 🙏🙏
I must concur that i have watched many DNA videos that explain how proteins are made and your video specifically was so much more coherent (travelling back a few times to make sure i understood correctly). I am now subscribed to your channel and making my way through all the things i want to learn. You sir are an amazing teacher!!!
Thankyou Ben, we really appreciate it and we're glad the video helped clarify things for you 😊
Do you guys knows how much I love you guys and seemingly help my school, career, and future just with your videos....
Your video was much easier to understand than all of the other ones I watched on this topic. Thank you!!
That was hands down the best explanation/demonstration of this process I´ve seen. Thank you so much! I´ve got an exam in a few weeks partially covering this and this video really helped!
IM A VISUAL LEARNER AND THIS HELPED ME SO MUCH, I just want to say how much I appreciate your resources as I’m in my GCSE year and trying to figure this out in lessons. You really are so underrated and should be acknowledged more, but just know you are helping so many people out there including myself to get the best grades possible and understand science and maths. Thank you 😊
Hi Maddie, so glad to hear you found this helpful! Thanks for leaving us a comment, it’s always such a pleasure to hear from people who are finding the vids useful. Good luck with all your work!
Perfect and simple explanation for someone with pretty much no background in biology but needed this information. Thanks a lot!
Thank you for breaking up this topic into small bits and explaining it. It is way clearer than what schools teach. I was so confused at first. Now I finally got it!
Thank you soooooo much, we've been busy with DNA for a week now and I still didn't understand ANYTHING but you made it so easy to understand
This is extremely useful, thanks. I have spent hours before trying to understand this and now I understand it in 10 minutes watching your video!
This was great for a broad beginner snap shot , I watched another video that was too complicated; naming all the enzymes and different structural names of t RNA molecule that the whole thing was confusing if not discouraging. Thank you for this video
this is the only thing that has helped me understand protein synthesis. no explanations, textbooks or other videos have helped me but now I actually get it so thank you for that!!
Never knew this was actually so easy. KEEP IT UP YOU'RE DOING WONDERS FOR US STUDENTS💕✨
thank you so much. i consulted so many videos and resources and even asked AI to explain it to me but no explanation helped, even after hours of trying to understand this idea of protein synthesis. thank you so much for making this video, i really think you just saved me.
I was completely lost in this topic ever since we started. We have the exam tomorrow and this is my saviour. I also sent it some friends, this is seriously the most coherent explanation I have found
THANKS A LOT SIR !!! I'VE BEEN WORKING OUT TO UNDERSTAND THIS IN LAST 3 HOURS AND NOW YOUR VIDEO HELPED ME TO UNDERSTAND IN 11MINUTES.
Wow this was the best conceptual overview of transcription and translation I have ever seen.
I cannot tell you how much this help me, I kept reading my damn notes and textbook trying to understand it and almost gave up, so I gave RUclips a try not expecting any good videos but then I found yours, you made everything make sense! Thank you, I will definitely be coming back to watch more of your videos.
Thank you so much Sydney, really glad it helped! 😊
Wow this really helped me I was stressing out on this transcript, then my friend comes along and tells me to watch this video, which clears up LOTS of things. THANK YOU SO MUCH!
Your videos are the only ones I am able to understand properly. Thank you so much for them. Would highly appreciate if you do A level videos on those topics.
Does anyone else watch his videos in 2 times speed?
twin~ where have u been~🎶🎶

biology textbooks are so hard to understand.. but your explanation with simple language and animations made me understand everything. Wish textbooks were like that. Thank you lifesaver
You are honestly the best teacher,can't thank you enough for your help. Could you please go through some past science papers if possible?
I can't thank you enough for this. I'm currently on a 7, and I'm trying to aim for an 8. The way you explain makes it really simple, and not many people know that you also have to understand the content, not just memorise it. This helped me understand greatly, as I've forgotten all of it. Thanks again, and I'll let you know what I get
I can't imagine why anyone could dislike this video - it was incredibly helpful, thank you so much!!
THANKYOU!!! I have been trying to learn about translation and transcription for weeks and a ten minute video explained it better that all the reserach I made throughout that time!! Loved everything, the visuals the explanation etc.
Really glad we could help, thanks Julieta 😊
Never comment on videos but this was so clear and useful, thank you so much for all you put into it! I love your channel and website and recommend it to everyone. Keep up the good work!
Very grateful for the comment, thanks Perele, glad you're enjoying the channel! 😊
simple, factual, straight to the point and most importantly very clear. great video
this video is so well-explained!! Thank you so much, this was so helpful!
thank u thank u thank u thank uuuu!!!!
learning this stuff i missed during lockdown, now, one day before my exams tomorrow
you’ll be the reason i get full marks in protein synthesis for my test in an hour thanks😜
THIS CHANNEL NEEDS MORE RECOGNITION
These videos really help me out, you always explain things so well! It suddenly becomes so much easier to understand when you explain it, thank you so much! I honestly LOVE your videos, thank you!
Happy to help Juliet! 😊
dearest mr cognito you have just pulled me and my friends through the 5 marker on protein synthesis in our igcse higher paper 2 you have saved lives and carried us all much love you biggest fans. u r a legend
what exam board+ paper was it
@@abcdefghijklmnopqrstuvwyxz102 it said both in the comment
Wow! This is awesome! You're really the best! I've been so confused but this your video is just the bomb! Thank you so much for a powerful explanation. Keep it up!
The best video on the subject i have seen so far. Now I have a better understanding of the process. Thank You
The best video I have ever seen that explains everything in detail and easily thank you so much better than any teacher i have ever had !!!!!!
God Bless you my brother, you have helped me so much here. That was the best, easiest way you have taught us about how proteins are made. Wherever you are atm in life, I hope your having the best time, I hope your living the dream and I hope everything you've ever wanted to accomplish, you have. Thankyou so much mate.
Thanks alot your description and explanation aswell visual presentation is very clear i understood this in just the span of 11 minutes wich is insane against the usual 5 hours people tried explaining the topic :)
i have a biology test in a few days and I haven't been able to understand protein synthesis for weeks thank you SO much you have no idea how much this helped me 💞💞
Really great to hear it helped - thanks!
With all honesty you are simply the best sir. Thank so much for helping me totally understand Protein synthesis. I have subscribed for more of your products
Thank you so much for explaining so clearly, you have no idea how frustrated ive been about this topic. and I love how you paused for a few seconds in between sentences which allows us to process the things you said. You helped me so much!!! thank you once again!
Ah thank you Mina! Really glad to hear you like the style of our videos 😊
thank you so much, this is so helpful! i finally understood this after being so confused in class!
just had 2 subscribe this helped so much keep up the good work dude
NOTES
Protein synthesis:
1. Transcription - taking a single gene of DNA and copying it into a structure called mRNA:
- Enzyme (RNA polymerase binds just before the gene starts)
- Two strands are separated, all the bases to be exposed
- RNA p. moves along the dna strand, reads the bases one by one, make mRNA strand
- mRNA bases will always be complementary to DNA bases
- Once done RNA p. detaches
- Original one is called template strand
2. Translation - taking that mRNA strand and using it to produce a protein:
- Triplet codes for a specific amino acid
- mRNA strand and a ribosome bind together
- Amino acids are brought to the ribosomes by tRNAs
- Anti-codon
- tRNA detaches leaving amino acids are in correct order forming a protein chain (folded up)
3. :
- Gene - a section of dna that has a specific sequence and codes for specific protein
- Specific sequence of amino acids be read by ribosomes
- DNA is very long so it can’t leave the nucleus, a copy of the specific gene should be made - mRNA (copy of a single gene)
- RNA: A-U, C-G
thx
Thanks
@@blakmomba7923 you got GCSEs this year too?
Thanks
This comment should be pinned
this video was SO helpful, i understood everything you said perfectly. thank you so much for this video, it's a life saver 💪
Thank you smmmm! I love your video about protein synthesis, I've been struggling a lot with this topic bc I couldn't understand it in class but now I got it, thank you for the great video
I love this channel, on the same sort of level as free science lessons
thiS THIS MAKES SENSE!!! it simplifies what's necessary while also going into detail about the things I wasn't clear on before!!! love it 10/10
That's our aim! Glad you enjoyed it 🙌
I have to leave a comment to say thank you. I finally understand! Definitely the best video on protein synthesis I have found, so clearly explained & easy to follow!
Ah thank you so much Hannah, we really appreciate the comment! Glad it helped 😊
Duke, you are a genius! I spent days to understand this concept but here everything is made easy and simplified. Thank you.
it was really difficult trying to learn this on my own but then this video has helped me out. Thank you so much
