Final answer:
The term used to describe the phenomenon in which a bacteriophage genome incorporates its genome into the chromosome of the host is lysogeny. In the lysogenic cycle, the phage genome integrates into the bacterial chromosome and becomes part of the host.
Step-by-step explanation:
In the lysogenic cycle, instead of killing the host, the phage genome integrates into the bacterial chromosome and becomes part of the host. The integrated phage genome is called a prophage.
During lysogeny, the prophage will persist in the host chromosome until induction, which results in the excision of the viral genome from the host chromosome. After induction has occurred, the temperate phage can proceed through a lytic cycle and then undergo lysogeny in a newly infected cell.
