Question

Which best describes the lytic and lysogenic cycles?
Unlike the lytic cycle, the lysogenic cycle involves production of virus particles.
Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.
Symptoms of infection appear in the lysogenic cycle but not in the lytic cycle.
For virulent viruses, the lysogenic cycle is the main way of replicating.

Answer 1

Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.

Explanation: In the lytic cycle the phage replicates, produces many new virions, and lyses (kills) the host cell. In the lysogenic cycle the viral genome integrates into the host chromosome (a prophage) and is replicated with the host without producing virions until it is induced to enter the lytic cycle.
