a)
Student 2 only
b)
Student 4 only
c)
Students 2 and 4 only
d)
Students 3 and 4 only
7.
Suppose that the transfer of genes between 2 bacteria was interrupted, that the last gene transferred was Gene A, and that no incomplete copies of a gene were transferred. Based on this information, Student 1 would say that transfer was most likely interrupted how many minutes after the transfer began?
a)
15
b)
30
c)
45
d)
60
