What usually happens to the host’s DNA during the lytic cycle? It is destroyed. It is integrated with the viral DNA. It becomes a provirus. It is deactivated.

It is destroyed

Explanation:

The lytic cycle of the viral life cycle is characterized by the destruction of the host's DNA. The infecting phage gains entrance into the host's cell synthesizes proteins that break down the host's DNA, and then utilizes its own DNA as the cellular DNA.

From there on, the phage takes over the cell's genetic mechanisms and utilizes it in the synthesis of the necessary proteins to manufacture new infecting structures.
