Which viral life cycle allows viral genetic material to lay dormant while the host cell reproduces?
A
lytic
B
mitosis
C
lysogenic
D
S phase
Explanation: 

Detailed explanation-1: -Lysogenic cycle. The lysogenic cycle allows a phage to reproduce without killing its host. Some phages can only use the lytic cycle, but the phage we are following, lambda ( ), can switch between the two cycles.

Detailed explanation-2: -Answer and Explanation: The cycle when a virus is dormant inside its host is called the lysogenic cycle. The lysogenic stage of the virus’s life cycle refers to the stage when the virus lies dormant or latent within a cell. This type of viral infection is often a persistent viral infection.

Detailed explanation-3: -While latency is considered a dormant state of the virus, recent studies identified lytic gene expression during latency (1–4).
