Detailed explanation-1: -The lytic cycle involves four steps: infecting a host (an action called exposure), injecting a cell with the virus’s genetic material, using the cell’s metabolic engines to create new viruses, and finally, weakening the cell walls until the host cell lyses, or bursts open from excessive internal pressure.

Detailed explanation-2: -So the correct option is ‘ Phage DNA integrates with host DNA’.

Detailed explanation-3: -In a lytic cycle, the virus introduces its genome into a host cell and initiates replication by hijacking the host’s cellular machinery to make new copies of the virus. Once infection is complete, the newly replicated and assembled virus particles are released through lysis of the host cell into the surrounding waters.
