Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What cycle causes the cell burst?
A
Lysogenic
B
Carbon
C
Lytic
D
Hydrologic
Explanation: 

Detailed explanation-1: -In the lytic cycle, a phage acts like a typical virus: it hijacks its host cell and uses the cell’s resources to make lots of new phages, causing the cell to lyse (burst) and die in the process.

Detailed explanation-2: -The lytic cycle (/ˈlɪtɪk/ LIT-ik) is one of the two cycles of viral reproduction (referring to bacterial viruses or bacteriophages), the other being the lysogenic cycle. The lytic cycle results in the destruction of the infected cell and its membrane.

Detailed explanation-3: -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-4: -3). In the lytic cycle, viral infection leads to near-immediate viral replication inside the host cell and results in cell lysis (bursting) upon the release of progeny virions.

Detailed explanation-5: -The difference between lysogenic and lytic cycles is that, in lysogenic cycles, the spread of the viral DNA occurs through the usual prokaryotic reproduction, whereas a lytic cycle is more immediate in that it results in many copies of the virus being created very quickly and the cell is destroyed.
