Question

Quizplus · Accepted Answer

Bacteriophages engage in two interactive cycles with bacteria known as the lytic and lysogenic cycles. In the lytic cycle, the phage infects the bacterial host cell, replicates its DNA and proteins, and then lyses (breaks open) the host cell, releasing new phages. In contrast, in the lysogenic cycle, the phage DNA integrates itself into the bacterial chromosome and becomes inactive, replicating along with the bacterial DNA as a prophage. The lysogenic cycle can later enter the lytic cycle and cause host cell lysis if triggered by certain stimuli.
