Detailed explanation-1: -Viruses may be virulent or temperate. Virulent viruses tend to kill their host upon entry through cell lysis whereas temperate viruses ‘restrain’ by not immediately causing cell lysis but replicating while in latent state.

Detailed explanation-2: -A virulent phage shows only the lytic cycle pictured here. In the lytic cycle, the phage replicates and lyses the host cell. The third stage of infection is biosynthesis of new viral components. After entering the host cell, the virus synthesizes virus-encoded endonucleases to degrade the bacterial chromosome.
