NEET BIOLOGY

Detailed explanation-1: -Viruses that infect bacteria, multiply and cause their lysis are called lytic cycle. The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses, the viruses then burst out of the cell.

Detailed explanation-2: -Hint: Bacteriophage is a kind of virus that can infect bacteria and start replicating inside the bacterial cell because the lysis represents the lytic cycle.

Detailed explanation-3: -The lytic cycle, or virulent infection, involves a virus taking control of a host cell and using it to produce its viral progeny, killing the host in the process.

Detailed explanation-4: -Bacteriophages cause the lysis of virus.

Detailed explanation-5: -In the lytic cycle, the phage replicates and lyses the host cell. In the lysogenic cycle, phage DNA is incorporated into the host genome, where it is passed on to subsequent generations. Environmental stressors such as starvation or exposure to toxic chemicals may cause the prophage to excise and enter the lytic cycle.
