Hi everyone!
I did some multiple choice tasks and got stuck on two statements:
"In RNA, the sugar is present in the 2'-endo conformation". This statement is false, but why? What conformation does the sugar molecule have? How do I recognize the conformation?
"When two nucleotides polymerize, pyrophosphate is released". This statement is correct, but why? Why is pyrophosphate released here? Do we simply not have a single phosphate group here that binds to the C3 atom, i.e., where the hydroxyl group is located? What does this have to do with the release of pyrophosphate? I thought there is no release. I can't imagine anything about it. Could you explain me these things ( graphically and with simple words)?
