Final answer:
Lysogenic viruses differ from lytic viruses by integrating into the host DNA, where they can remain dormant, while lytic viruses lead to immediate host cell destruction and virus propagation.
Step-by-step explanation:
b) Integration into host DNA Lysogenic viruses are different from lytic viruses in that they integrate their genetic material (usually DNA) into the host cell's DNA. This integrated viral DNA is called a prophage. During the lysogenic cycle, the viral genome becomes a part of the host cell's genome and replicates along with it. This integration allows the virus to remain latent within the host cell for an extended period without causing immediate cell destruction. In contrast, lytic viruses follow a more immediate and direct process of host cell destruction, involving the production of new viral particles and the subsequent lysis (burst) of the host cell to release the progeny.
