What Are The Function Of DNA Polymerase 1/2 And 3?

What Are The Function Of DNA Polymerase 1/2 And 3? DNA polymerase 1, 2 and 3 are prokaryotic DNA polymerases involved in DNA replication. Pol 1 catalyzes the repairing of DNA damages. Pol 2 catalyzes the fidelity and processivity of DNA replication. Pol 3 catalyzes the 5′ to 3′ DNA polymerization. What is the function
