In the mating Hfr met- his+ leu+ trp+ × F- met+ his- leu- trp-. The met marker is known to be transferred very late. After a short time, the mating cells are interrupted and the cell suspensions plated on four different growth media. The amino acids in the growth media and the number of colonies observed on each are as follows:
histidine + tryptophan 250 colonies
histidine + leucine 50 colonies
leucine + tryptophan 500 colonies
histidine 10 colonies
What is the order of transfer of the genes
