Question

I am having trouble in understanding this question. The second photo is part b of the question. Any help would be appreciated!

Four Hfr strains of E.ole known to transfer thier genetic material during conjugation in different sequences. Given the time of entry of the markers into the F-recipient, construct a genetic map which includes all of these markers, starting with arg as number 1 and phe as number 11.(Not all markers were assayed in each strain, remember the E.coli chromosome is circular and the distance between genes will be equal to the time difference between genes.) Strain 1 Markers: arg - thy - met - thr Tiine in minutes: 15 21 3248 Strain 2Markers: mal - met - thi - thr - try Time in minutes: 10 17 233 57 Strain 3 Markers: phe his - bio - azi - thr - thi Tune in minutes: 6 11 33 48 49 60 Strain 4 Markers: his phe - arg - mal Time in minutes: 18 23 35 45 B.
