Webb6 apr. 2024 · INTRODUCTION. DNA apurinic/apyrimidinic (AP) sites are a major DNA lesion generated under normal growth conditions as a result of spontaneous or DNA glycosylase catalysed hydrolysis of N-glycosidic bonds between the base and deoxyribose backbone (). N-glycosidic bonds with purines, especially guanine, are liable to undergo spontaneous … Webb27 apr. 2024 · 1) DNA Polymerases-I. DNA polymerase I in prokaryotes is far from irrelevant, however.This enzyme serves as a host of “Clean-up” functions during replication, recombination, and repair.. These special functions are enhanced by an additional enzymatic activity of DNA polymerase I, a 5’->3’ exonuclease activity.
