In both prokaryotes and eukaryotes, highly-conserved mismatch-repair systems both correct DNA replication errors, by coupling recognition of DNA mismatches to identification and excision of the mutated nascent DNA, and interact with recombination mismatches and a variety of DNA lesions. Evolution of single prokaryotic recognition (MutS) and coupling (MutL) proteins into multiple specialized eukaryotic proteins has accompanied expansion of their genomic-stability functions.
