Question

The giant sandworms of the planet Arrakis harbor a gut bacterium that undergoes conjugation. However, the conjugation lasts for 200 minutes. You perform an interrupted mating experiments and find that following markers are transformed at the respective times: ple 25 minutes, bar 75 minutes, gap 100 minutes, zap 150 minutes and chr 200 minutes.

Draw a genetic map of the bacterium assuming a linear transfer rate of DNA. You also find that the plemarker is transferred at a higher rate than the chr marker. What is the explanation for this phenomenon?

Finally if you use a different Hfr that begins the transfer just after zap, what difference in transfer times would you expect between chr and ple?
