A test of the CoHR motif associated with meiotic double-strand breaks in Saccharomyces cerevisiae.

Meiotic recombination is not random along chromosomes; rather, there are preferred regions for initiation called hotspots. Although the general properties of meiotic hotspots are known, the requirements at the DNA sequence level for the determination of hotspot activity are still unclear. The sequence of six known hotspots in Saccharomyces cerevisiae was compared to identify a common homology region (CoHR).
