The transition in the mitotic cell cycle to meiosis includes substantial modifications in mechanisms of DNA double strand break (DSB) repair by homologous recombination (HR).Most mitotic HR repairs spontaneous lesions, and most repair merchandise are noncrossovers (NCOs) that don’t involve exchange of flanking parental sequences (Kadyk and (+)-Benzetimide Biological Activity Hartwell, Ira et al ^ques et al).In contrast, meiotic recombination is initiated by programmed DSBs Pa (Cao et al Sun et al) that typically are repaired as crossovers (COs) between homologous chromosomes (homologs), with exchange of flanking parental sequences.Interhomolog COs, combined with sister chromatid cohesion, build physical linkages that guarantee faithful homolog segregation for the duration of the first mei.
