Solution
The correct option is D Lysogeny
The phenomenon by which the phage DNA exists as part of the host DNA is known as lysogeny. The latent form of the virus genome remains within the host but does not destroy it, is called as the prophage. Episome is a genetic element inside some bacterial cells, especially the DNA of some bacteriophages, that can replicate independently of the host and also in association with a chromosome with which it becomes integrated. The lytic cycle is one of the two cycles of viral reproduction, the other being the lysogenic cycle. The lytic cycle results in the destruction of the infected cell and its membrane. Thus, the correct answer is option B.
