Pair formation ability in mating mixture of synchronized Hfr or F- culture and asynchronous culture of appropriate partner was studied. The obtained results allow to conclude that the pair formation ability of F- cells is stable over the whole cell cycle whereas in Hfr cells is it subject to cyclic changes with maximum in the first half of the cycle.
