During the lytic infection by a virus, the host cell is-
A
destroyed
B
copied
C
passed on to the lysogenic cycle
D
not affected
Explanation: 

Detailed explanation-1: -The host cell is destroyed in the lytic cycle. The lytic cycle is a mode of viral replication in which a virus produces many copies of itself in the host cell and those copies proceed to burst the host cell on their way out. This bursting destroys the cell and may cause some of the symptoms of the viral infection.

Detailed explanation-2: -In the lytic cycle, the virus attaches to the host cell and injects its DNA. Using the host’s cellular metabolism, the viral DNA begins to replicate and form proteins. Then fully formed viruses assemble. These viruses break, or lyse, the cell and spread to other cells to continue the cycle.

Detailed explanation-3: -A bacteriophage is a type of virus that infects bacteria. In fact, the word “bacteriophage” literally means “bacteria eater, ‘’ because bacteriophages destroy their host cells.

Detailed explanation-4: -Answer and Explanation: During a lytic infection of a virus the host cell lyses, or bursts. The lytic cycle of a virus begins when a virus locates and enters a living organism. The virus attaches itself to a cell that’s known as the host cell.
