Strand transfer enzyme RecA [77], is expressed in each mitosis and meiosis. DMC1 has larger affinity for binding ssDNA and RAD51 types helical nucleoprotein filaments that promote strand invasion and formation of heteroduplex DNA [78]. These two proteins co-localize in recombination spots in an equimolar ratio throughout pachytene, and due to the fact both have the capability for protein interacti
