19. In which reproductive cycle of the virus does the viral DNA integrates with the host DNA? Lytic Cycle Lysogenic cycle Life Cycle Apoptosis Cycle

The correct answer is the Lysogenic cycle. In this cycle, the viral DNA integrates with the host DNA and becomes a part of the host genome. This integration allows the virus to replicate along with the host cell's DNA during cell division. The viral DNA remains dormant in the host genome until certain triggers activate it to enter the lytic cycle, leading to the production of new viral particles.
