Homologous recombination, an exchange between DNA strands, plays a role in the maintenance of genome stability and the production of genome diversity. While, in mitosis, it is required for the repair of DNA damage, it is for the segregation of homologous chromosome at meiotic division I. Meiotic recombination is coupled with chromosome morphogenesis and is under a strict control. Malfunction of the recombination leads cancer and infertility in human. In order to reveal molecular mechanism of the recombination, we have been analyzing genes and proteins involved in the process using molecular, genetical and biochemical methods.
