Abstract
Translesion DNA synthesis (TLS) is a fundamental biological process whereby arrested DNA replication caused by the presence of base damage that cannot be readily bypassed by replicative DNA polymerases, is relieved by an alternative DNA replication that utilizes DNA polymerases that are specialized for DNA synthesis past such lesions. Multiple such polymerases have been identified in all life forms. In particular, vertebrate cells contain no less than 10 such specialized enzymes. This article reviews our present knowledge of these specialized DNA polymerases in general and their specific role in TLS.
