Final answer:
Lysogeny is a process in which a bacterium is infected by a temperate phage and the phage genome integrates into the bacterial chromosome, forming a prophage. The prophage remains dormant and replicates along with the bacterial chromosome. Lysogeny can lead to phenotypic effects on the bacterium.
Step-by-step explanation:
Lysogeny is a process in which a bacterium is infected by a temperate phage, resulting in the integration of the phage genome into the bacterial chromosome. This integrated phage genome is called a prophage. During lysogeny, the prophage remains dormant and replicated along with the bacterial chromosome during cell division. Lysogeny can have phenotypic effects on the bacterium, such as introducing new genes or enhancing virulence.
