Question

E. coli DNA polymerases II and III lack which activity ?

Answer 1

DNA polymerase II, a family B polymerase, is a polB gene product also known as DnaA. Pol II has 3'–5' exonuclease activity and participates in DNA repair, replication restart to bypass lesions, and its cell presence can jump from ~30-50 copies per cell to ~200–300 during SOS induction
