- Compare and contrast conjugation involving an F+ donor, an Hfr strain, and an F' donor.arrow_forwardA particular Hfr strain normally transmits the pro+marker as the last one in conjugation. In a cross of thisstrain with an F− strain, some pro+ recombinants are recovered early in the mating process. When these pro+cells are mixed with F−cells, the majority of the F− cellsare converted into pro+ cells that also carry the F factor.Explain these results.arrow_forwardAn Hfr strain that is leuA+ and thiL+ was mixed with a strain thatis leuA− and thiL−. In the data points shown in the following graph,the conjugation was interrupted at different time points, and thepercentage of recombinants for each gene was determined bystreaking on a medium that lacked either leucine or thiamine.What is the map distance (in minutes) between these two genes?arrow_forward
- What is the result of conjugation between F and F cells?arrow_forwardWith the technique of interrupted mating four Hfr strains were tested for the sequence in which they transmitted a number of different genes to an F strain. Each Hfr strain was found to transmit its genes is a unique sequence, as shown in the accompanying table. What is the gene sequence in the original strain from which these Hfr strains were derived?arrow_forwardList all major differences between (a) the F+ * F- and the Hfr * Fbacterialcrosses; and (b) the F+, F-, Hfr, and F' bacteria.arrow_forward
