  1. your videos are amazing.. I use it on my teaching job as a science teacher here in the Philippines keep posting more videos 🙂 God bless

  2. But should not one codon codes one amino acid only? In the table you showed us at the end of the video, it seems that more than one codon actually code for the same amino acid…

  3. When he was decoding the gene, the lower strand had UU… and this doesn’t make sense to me, because from what I know a DNA has no Uracil, it has thymine instead

  4. Your the best! My bio teacher has us watch your videos so much and it’s sooo helpful .for once I understand biology!

  5. I'm sure you're decoding the gene wrong? Don't you have to turn the mRNA into the tRNA molecule first before then translating to the amino acid?

  6. Always good stuff from Paul! This video explains the relationship between tRNA and mRNA: https://www.youtube.com/watch?v=R2qStDhc7xQ&t=30s

  7. A thousand thank you's, Mr. Andersen. You are getting me through my college biology course. I wish all instructors had the ability to break things down and explain them in easily understandable ways. You are a very talented educator. Also, you rock!

  8. well explained. I teach anatomy and will tel students to use your videos if they are confused. I am also in grad school and use you videos when I don't understand the material Thanks!

  9. I have been watching these videos since AP Bio junior year of high school. Still watching them now as a Bio major in college!!!

  10. u r helping me study biology which i do not utterly understand while learning in class…well i think that's great keep doing more videos……..

  11. Amazing video.
    You should mention how RNA polymerase forms the mRNA strand using free floating nucleotides.

  12. Thank you sir you helped me finish my essay in the hour before it was late 😰😇
    I decided to explain baking Brownies in Transcription & Translation process.

  13. I N T E L L I G E N T DESIGNER……"THE F O O L HAS SAID ION HIS HEART THEIR IS NO GOD" CHRIST IS THE WORD OF GOD FROM ETERNITY PAST UNTO ETERNITY FUTURE…..EVOLUTION EVEN IN THE LATER WORDS WAS ONLY THEORY AND INTELLIGENT DESIGN WAS INEVITABLE…..THE ABSURDITY AND UNPROVEN T H E O R Y of evolution IS THE GOD OF SCIENCE WHICH SMART BUT ARROGANT MEN HAVE GIVEN CREDIT FOR THE AMAZING ORDER OF BOTH ATOMIC AND CELESTIAL Scale….THEY WILL BELIEVE ANY T H E O R Y …..AS LONG AS IT DOES NOT GIVE CREDIT FROM THE GOD OF ALL
    THINGS….THE MICRO TO THE MACRO OF ALL DESIGN….ONE CREATOR OF ALL NOT HUNDREDS OF SEPARATE CAUSE AND EFFECT OR CHANCE "THINGS"…..THEY WILL ONLY UNDERSTAND AS THEY ARE
    HUMBLED TO AT THE JUDGEMENT OF THEIR DENIAL …..TIME FOR LAMENTED IS TOO LATE THEN HUM-BLE YOURSELF N O W THAT GOD CAN EXALT YOU LATER……CHRIST JESUS IS THE ONLY WAY, TRUTH
    AND LIFE…..TO RECONCILE OUR EVIL DEEDS TO FORGIVENESS THROUGH CHRIST BLOOD AT CALGARY.
    TRUST JESUS ,HE ALONE CAN SAVE YOUR SOUL AND FREE YOU FROM SIN HERE IN THIS REALM…!!!!!!

  14. Where does Replication take place? Translation takes place in the cytoplasm and Transcription takes place in the nucleus but what about DNA replication? Before Transcription there is DNA Replication. I'm getting confused between the two.

  15. Was it Franklin that came up with the structure of the DNA, or at least she made the break through that it was a double helix. Then Watson & Crick built off of her work? I'll study more! I know the answer is at my fingertips.

  16. that's one a helpful video, but i think the part when you say that introns are the sections of mRNA that don't code for protein is kind of swapped with exons, cuz i think it should be exons instead of introns

  17. And this system was made by chance by random atoms and molecules. Lol even if you give a billion billion years of time and building block molecules already prepared, random chance can not make this system. We humans, who know how this works and have science and technology cant even make this from scratch.

  18. Truly, you are such an incredible teacher! My Biological Anthropology professor is always showing your videos in class. She’s brilliant as well and she greatly enjoys your videos, as do I. I do have a question about this video. Your last screen of images has two rows of letters at the top left and you wrote on the top right that those represent DNA. I was wondering why the DNA has uracil bases towards the end of the bottom of the two rows/strands?

  19. I'm reasonably certain that every high school/college bio student has watched these videos at some point

  20. I've been struggling with this topic for a while, and it finally clicked! Just in time for my Bio final :')
    Thank you so much Mr. Anderson

  21. Thank you for simplifying Biology topics so that is makes studying details easier brotha!!! Cellular/molecular final is coming up…thaank you for all the help

  22. Paul, for the example of a gene sequence on DNA, the stop sequence should be ATT and not AUU. DNA doesn't have Uracil. Thanks for all videos that you are posting. They are very helpful.

  23. Ok the flex commercial is disgusting. Change the ads. Talking about smelly periods? If you can’t wait 5 days to have sex you need to get a mental evaluation. I’m just grossed tf out
