This is the second time I post this question. I got an incorrect answer, so I had to post it again.... Please read the question; you need to draw.

8. In order to determine the overall chromosome map for a new wild type strain of E. coli, three Hfr strains were obtained by independent insertions of the F factor. The start times of transfer of several genes were determined during conjugation matings between each Hfr strain and an F recipient carrying six auxotrophic mutations Time (min) of marker transfer 2 Hfr Strain: Gene Ade His 15 15 37 65 35 13 50 40 10 Lys Bio Met 30 20 45 A. Using the times taken to begin transfer of each marker, draw a unified chromosome map of the chromosome of this strain of E. coli, showing its total length in minutes of transfer and the order and relative distances between these markers B. Show the position and orientation of the F factor in each Hfr strain.

Explanation / Answer

Short time duration represents the marker is near the start codon and longest time duration represents the codon present at end of the sequence.
