Evolutionary analyses of DNA sequences subject to constraints of secondary structure.

abstract：:We used ends-in gene targeting to generate knockout mutations of the nucleosome assembly protein 1 (Nap1) gene in Drosophila melanogaster. Three independent targeted null-knockout mutations were produced. No wild-type NAP1 protein could be detected in protein extracts. Homozygous Nap1(KO) knockout flies were either em...

abstract：:In diploid eukaryotes, repair of double-stranded DNA breaks by homologous recombination often leads to loss of heterozygosity (LOH). Most previous studies of mitotic recombination in Saccharomyces cerevisiae have focused on a single chromosome or a single region of one chromosome at which LOH events can be selected. I...
