We describe a highly efficient method for exact gene replacement in budding yeast. Induction of rapid and efficient recombination in an entire cell population results in at least 50% of the recombinants undergoing a switch of the endogenous copy to a specific mutated allele, with no remaining markers or remnant of foreign DNA, without selection. To accomplish this, a partial copy of the replacement allele, followed by an HO cut site, is installed adjacent to the wild-type locus, in a GAL-HO… CONTINUE READING
