Introduction the ability of all organisms to replicate their genomes is a pre-requisite for life in order to accomplish this with maximum efficiency and fidelity. Dna repair has been regarded as an important barrier to carcinogenesis the newly discovered field of translesion synthesis (tls) has made it apparent that mammalian.
Ultraviolet-induced 6-4 photoproducts (6-4pp) and cyclobutane pyrimidine dimers (cpd) can be tolerated by translesion dna polymerases (tls pols) at stalled. Thus, the exonuclease activity can also act as a kinetic barrier to translesion synthesis (tls) by preventing the stable incorporation of bases opposite dna lesions.
