Question

explain the functions of DNA polymerase 1 2 AND 3?

Answer 1

DNA Polymerase 1 - repair polymerase involved in excision repair with 3' - 5' and 5' - 3' exonuclease activity. Present in prokaryotes.

DNA Polymerase II - 3' - 5' exonuclease activity, involved in DNA repair, replication restart to bypass lesions

DNA Polymerase III - holoenzyme, primary enzyme involved in DNA replication in E,Coli
