This is actually something thats worth knowing about. Most professors just teach the order in which happens and its components but I personally never heard about the approximate speed and how much does proofreading actually lowers the margin of error. Thank you very much for sharing!

Hey, I think you’re correct in terms of the speed clocked for e.coli;however I think that human polymerase adds nucleotides at an average of 100 bpps. It’s significantly slower but still very fast . I could be wrong but it’s worth double checking . Great video nonetheless, they’re immensely helpful!
