<span>The phage nucleic acid enters the host cell and becomes integrated part of bacterial genome called prophage and behave like a segment of the host and replicates along with it does not cause lysis</span>
Virus completes through two major cycles known as a lytic and lysogenic cycle. In the lysogenic cycle, the virus genome or genome of phage enters the host cell through the attachment and penetration. Unlike the lytic cycle, it integrates into the host genome (chromosome) and becomes part of the bacteria.
Such bacteria called lysogen. it is the typical nature of the phage to be inactive or latent within the host cell and replicate with the host genome and pass to the daughter cell. The lysogenic cycle can change the host phenotype due to phage's conversion.
The lysogenic cycle occurs due to the unfavorable condition for the virus so that remains inactive and replicate with the host genome and transferred to the daughter cells.
