You perform interrupted-mating experiments on three hfr strains (a, b, and c). genes are transferred (from last to first) in the following order from each strain: strain a, thi-his-gal-lac-pro; strain b, azi-leu-thr-thi-his; strain c, lac-gal-his-thi-thr. how are the f factors in these strains oriented?
