Full Answer

Such a phage is known as a lysogen, and it is said to display lysogeny. The phages can integrate their complete genetic information (genome) into that of the bacteria that host them, and a temperate phage can infect the host bacteria. On infecting the bacteria, it can either behave like virulent phage by entering into the lytic cycle or can get into a symbiotic relationship with the hosting bacteria. When behaving in the latter way, the phage is carried on to the descendants of the hosting bacteria.
