A bacterial chromosome has four markers,A,B,C,and D,evenly spaced throughout the circle.A generalized transducing phage will:
A)always transduce at least two of the four markers.
B)never transduce more than one marker.
C)transduce any of the markers by different transduction events.
D)transduce only one specific marker such as A.
E)pick up all the markers in one particle.

Question

Quizplus · Accepted Answer

A generalized transducing phage can pick up any part of the bacterial chromosome and transfer it to the recipient cell. Therefore, it can transduce any of the markers by different transduction events. It is not limited to transducing only one specific marker or all the markers in one particle. It is also possible to transduce more than one marker in a single event, but it is not always guaranteed. Therefore, choice C is the best answer.
