Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which viral life cycle kills its host cell by lysing?
A
lytic
B
mitosis
C
lysogenic
D
S phase
Explanation: 

Detailed explanation-1: -The lytic cycle: The phage infects a bacterium, hijacks the bacterium to make lots of phages, and then kills the cell by making it explode (lyse).

Detailed explanation-2: -Assembly-The host cell assembles the components into new copies of the virus. Lysis-The cell bursts open, resulting in its death and also in the release of more of the virus which can now go on to infect other cells.

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.
