1. Prophage

   A prophage is a bacteriophage (often shortened to "phage") genome that is integrated into the circular bacterial chromosome or exists as an extrachromosomal plasmid within the bacterial cell. Integration of prophages into the bacterial host is the characteristic step of the lysogenic cycle of temperate phages. Prophages remain latent in the genome through multiple cell divisions until activation by an external factor, such as UV light, leading to production of new phage particles that will lyse the cell and spread. As ubiquitous mobile genetic elements, prophages play important roles in bacterial genetics and evolution, such as in the acquisition of virulence factors.

1. Prophage

   A prophage is a phage genome inserted and integrated into the circular bacterial DNA chromosome or existing as an extrachromosomal plasmid. This is a latent form of a bacteriophage, in which the viral genes are present in the bacterium without causing disruption of the bacterial cell. Upon detection of host cell damage, such as UV light or certain chemicals, the prophage is excised from the bacterial chromosome in a process called prophage induction. After induction, viral replication begins via the lytic cycle. In the lytic cycle, the virus commandeers the cell's reproductive machinery. The cell may fill with new viruses until it lyses or bursts, or it may release the new viruses one at a time in a reverse endocytotic process. The period from infection to lysis is termed the latent period. A virus following a lytic cycle is called a virulent virus. Prophages are important agents of horizontal gene transfer, and are considered part of the mobilome. All families of bacterial viruses with circular DNA genomes or replicating their genomes through a circular intermediate have temperate members.
