Creating genetic map including time distance | Free AI Content | Essay Helper
Three Hfr strains of E. coli are known to transfer their genetic material during conjugation in different sequences. Given the time of entry of the markers into the F- recipient, construct a genetic map, including time distances, which includes all of these markers, starting with C as number 1 and F as number 6. (Not all markers were assayed in each strain and remember the E.coli chromosome is circular.)
Strain 1 Markers C – B – E – D
Time (min) 1 5 14 18
Strain 2 Markers A – E – D – F
Time (min) 3 15 19 30
Strain 3 Markers B – A – F
Time (min) 5 8 14
