Interrupted mating experiments were performed using three different Hfr strains (1-3). The three strains have different combinations of selectable markers. The time of entry for markers for each strain is shown is shown in the table given.
|
Hfr 1 |
Phe (5) |
Trp (35) |
Met (50) |
Ala (52) |
|
Hfr 2 |
Trp (2) |
Val (12) |
His (57) |
Pro (87) |
|
Hfr 3 |
Ala (10) |
Met (12) |
Val (37) |
Phe (57) |
Using the above data, predict the correct sequence of markers on the E. coli chromosome
