nicks introduced into partially depurinated pm2 dna by drosophila ap endonuclease i did not support dna synthesis by e. coli dna polymerase i , whereas nicks created by ap endonuclease ii were able to support dna synthesis , but at a rate far less than that observed for nicks introduced by e. coli endonuclease iv .
