What is the mechanism of RNA synthesis catalyzed by RNAPs?
a) The reaction occurs between the 5'-OH group of a ribonucleotide and the phosphate group of the 3' carbon of the ribonucleoside triphosphate to be incorporated.
b) The reaction occurs between the 3'-OH group of a ribonucleotide and the phosphate group of the 5' carbon of the ribonucleoside triphosphate to be incorporated.
c) The reaction occurs between the 5'-OH group of a ribonucleotide and the phosphate group of the 5' carbon of the ribonucleoside triphosphate to be incorporated.
d) The reaction occurs between the 3'-OH group of a ribonucleotide and the phosphate group of the 3' carbon of the ribonucleoside triphosphate to be incorporated.
A reação catalisada pelas RNAPs é mecanisticamente idêntica à reação catalisada pelas DNA polimerases.
A reação de adição ocorre no sentido 5'→3' e a fita de DNA molde (copiada) é aquela de sentido 3'→5'.
O ribonucleotídeo, para ser incorporado, deve ter como característica a complementariedade ao desoxirribonucleotídeo do DNA-molde.
