Base excision repair is a DNA repair mechanism that acts on single bases damaged by chemical modification. The repair pathway consists of several enzymes: (1) DNA polymerase I, (2) DNA ligase, (3) DNA glycosylase, (4) apurinic/apyrimidinic endonuclease, and (5) excision exonuclease. The correct order in which these enzymes act is:
