Novel partitioning of DNA cleavage sites for Drosophila topoisomerase II.

abstract：:Meiotic recombination occurs preferentially between homologous nonsister chromatids rather than between sisters, opposite to the bias of mitotic recombinational repair. We have examined formation of joint molecule recombination intermediates (JMs) between homologs and between sisters in yeast strains lacking the meiot...
