Quizplus · Accepted Answer

When the bacteriophage DNA becomes part of the bacterial chromosome, it has entered the lysogenic cycle. This means that the bacteriophage DNA becomes incorporated into the host cell's genome and is replicated along with the bacterial DNA during cell division. The bacteriophage can remain in this state for many generations until a trigger, such as stress or damage to the DNA, causes the virus to become active and enter the lytic cycle, where it replicates and eventually kills the host cell. However, the bacteriophage can also remain in the lysogenic cycle indefinitely, passing its DNA on to daughter cells as the bacteria divide.
