Here is the link to the updated version of this presentation. The updated version is shorts and contains a much better animation of transcription. • RNA Transcription (upd...
the way you do the video is simple but very clear and straight to the point! It really helps me out a lot to have a logic understand of my first nursing subject - Human Anatomy & Physiology. I feel I can learn it after watching video
Hi Kyle, I am a university student about to start my medical degree. I have to say, you provide the most comprehensive and accessible explanations of complex scientific ideas I've ever experienced in my whole undergraduate university degree at a prestigious university. Julia
I am confused by this video and video one. You stated in video one that the emzyme that cuts or splits DNA is called helicase and enzyme polymerase joins nucleotides back together like glue. Please help!
+whitnee Lewis Ah yes. I get that question a lot in class. I hope I can explain. During the process of DNA Replication, the double helix is split apart by an enzyme named "DNA Helicase" and is rejoined by an enzyme called "DNA polymerase." But during the process called transcription, the double helix is split apart by a different enzyme named "RNA polymerase." Hope that helps.
@@BeverlyBiology So DNA Helix is first split by DNA Helicase and then rejoined by DNA Polymerase, while RNA is split by RNA Polymerase and of course doesnt need to be joined because RNA strand will go out to the Ribosome is it right?
nice, simple yet comprehensive explanation.... Does DNA replication and transcription happen alternatively? (transcription...immediately followed by replication and so on)
I am a novice in this subject, but find it extremely fascinating. The presentation is of very high quality. However certain questions have arisen in my mind. They are as stated below: Do RNA Polymerase splits the entire DNA double helix or only a part of it? If yes, how does it decides which part of it is to be split open to start the process of creation of mRNA? How is it decided which section has to be split as this will lead to different protein synthesis? Is there any specific trigger to start synthesis of various different proteins at different instant?
you are a LIFESAVER!! im taking AP bio and i was not able to understand transcription no matter what i did and now i finally get it. thank you so so much you are amazing !!
