During the lysogenic cycle of a viral infection, the virus inserts its genetic material into the DNA of the host cell. The viral DNA then becomes a part of the host cell's DNA and remains dormant, replicating along with the host DNA as the host cell divides and grows. The virus does not immediately produce new viral particles or cause the host cell to burst and die. Instead, the virus remains hidden and replicates along with the host cell's DNA until it is triggered to enter the lytic cycle, where it starts actively producing new viral particles and ultimately causes the host cell to burst and release the newly formed viruses.
So which answer
"The virus hides in the host cell’s DNA" is the correct answer for what happens during the lysogenic cycle of a viral infection.
