Abstract
During meiotic recombination in the yeast Saccharomyces cerevisiae, heteroduplexes are formed at a high frequency between HIS4 genes located on homologous chromosomes. Using mutant alleles of the HIS4 gene that result in poorly repaired mismatches in heteroduplex DNA, we find that heteroduplexes often span a distance of 1.8 kb. In addition, we show that about one-third of the repair tracts initiated at well-repaired mismatches extend 900 bp.Entities:
