mismatch repair (medicine)


mismatch repair
<molecular biology> A DNA repair system that detects and replaces wrongly paired, mismatched, bases in newly replicated DNA. E. Coli has a mismatch correction enzyme coded for by three genes mutH, mutL and mutS, that is directed to the newly synthesised strand and removes a segment of that strand including the incorrect nucleotide. The gap is then filled by DNA polymerase.
