So I understand that DNA polymerase has a small binding pocket helps it distinguish dNTP and riboNTP. What mechanism does the RNA polymerase use to distinguish riboNTP and dNTP, U and T? Any papers I can refer to?


Thanks

I think the best thing to do is go to a second hand book store and buy a molecular biology handbook.

Here's a hint: It's not a mechanism that distinguishes U and T, it's morphology. And the morphology of a protein is influenced by... [;)]
