Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is the best description of the lytic cycle?
A
The viral reproductive cycle where the dividing viruses eventually cause the cell to burst
B
The viral reproductive cycle where the nucleic acid that is injected into the host is integrated into the hosts DNA
C
The viral reproductive cycle where a virus injects its plasmic into another virus impregnating it
D
The viral reproductive cycle where a virus engages in binary fission to produce multiple clones of itself
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: -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-4: -Viruses can be released from the host cell by lysis, a process that kills the cell by bursting its membrane and cell wall if present. This is a feature of many bacterial and some animal viruses.
