Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
define lytic cycle
A
type of virus infection, virus goes in and replicates and bursts.
B
type of virus infection, virus goes in and integrates into host genome.
Explanation: 

Detailed explanation-1: -The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within.

Detailed explanation-2: -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.

Detailed explanation-3: -The lytic cycle is named for the process of lysis, which occurs when a virus has infected a cell, replicated new virus particles, and bursts through the cell membrane. This releases the new virions, or virus complexes, so they can infect more cells.

Detailed explanation-4: -The new viruses burst out of the host cell during a process called lysis, which kills the host cell. Some viruses take a portion of the host’s membrane during the lysis process to form an envelope around the capsid. Following viral replication, the new viruses may go on to infect new hosts.
