1. To determine the overall chromosome map for E. coli, three Hfr strains ( #1 , 2 , \& 3) were obtained from F+ ancestors. The start times of transfer during conjugation matings with F strains carrying auxotrophic, resistance, and fermentation markers were determined for each Hfr strain, as listed. A. Using the times for transfer, draw a unified chromosome map of E. coli, showing the order and relative distances among these markers. B. Place the origin of transfer (site of F insertion) on the map for each Hfr strain. C. What is the total length of the E . coli genome, in minutes of transfer time
