Question

This assignment is worth: 100 pt Question 50 (of 52) 50. Award: 1.92 out of 1.92 points Show correct answer Shown below are the results of a series of coinfections using T4 rll- strains similar to those employed by Benzer. Each strain contains a different deletion mutation. Ability to produce wild-type progeny phage is indicated by (t). (o) indicates no wild-type progeny indicate the gene order that is most consistent with these data. Notice that the position of gene E has already been provided for you B E

Explanation / Answer

In this case we can see that mutation in ‘a’ recombines with b and e and not with c and e.

Similarly, b recombines with deletions a. c combines with d and e. d combines with a and e. and e combines with d.

any mutation that recombines with deletion 1 must be to the left of the deletion, any mutation that recombines with deletion 2 must be to the left of deletion 2, and so forth.

so,

the gene order will be
