Dna polymerase’s ability to slide along the dna template allows increased processivity all three translesion synthesis polymerases, along with rev1. 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. Find the latest research, reviews and news about translesion synthesis from across all of the nature journals. The information necessary for the proper functioning of cells is stored in genomic dna thus, it is crucial to maintain its integrity during cell division to.

A new type of review journal, featuring comprehensive collections of expert review articles on important topics in the molecular life sciences. Translesion synthesis (tls) is a dna damage tolerance process that allows the dna replication machinery to replicate past dna lesions such as thymine dimers or ap. Often when dna is damaged, the cell chooses to replicate over the lesion instead of waiting for repair ( translesion synthesis) although this may lead to mutations.
