Question: what is the function of dna polymerase 1 in dna replication?
Answer: DNA polymerase I functions to fill DNA gaps that arise during DNA replication, repair, and recombination. DNA polymerase II also functions in editing and proofreading mainly in the lagging strand (Kim et al. 1997, Wagner and Nohmi 2000). DNA polymerase III is the main replicative enzyme.
