Abstract

Method for removing DNA molecules containing one or more polymerase-generated mutations in a population of enzymatically amplified DNA duplexes comprising the steps of denaturing and reannealing the population of DNA duplexes, contacting the reannealled DNA duplexes with a mismatch repair system such that each strand is cleaved in DNA duplexes containing a base pair mismatch, and separating the cleaved DNA duplexes from uncleaved DNA duplexes.
