A full length cDNA of hREV3 is predicted to encode DNA polymerase ζ for damage-induced mutagenesis in humans. coli; yet cells lacking Pol I have been found suggesting Pol I activity can be replaced by the other four polymerases.

Given the error-prone disposition of PrimPol, we propose a mechanism whereby SSBs greatly restrict the contribution of this enzyme to DNA replication at stalled forks, thus reducing the mutagenic potential of Retrieved 2014-06-28. ^ Goodman MF (2002).

Articles by Ehlinger, A. It is important to note that the directionality of the newly forming strand (the daughter strand) is opposite to the direction in which DNA polymerase moves along the template strand. This is done by forming complexes of polymerase δ or ɛ with proliferating cell nuclear antigen (PCNA) and replication factors RP-A and RF-C. More about the author Izv.

Enzymes, helicase and topoisomerase II, are required to unwind DNA from a double-strand structure to a single-strand structure to facilitate replication of each strand consistent with the semiconservative model of DNA
