Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which viral replication cycle does not immediately begin replicating viral parts?
A
Lytic
B
Lysogenic
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -There are two processes used by viruses to replicate: the lytic cycle and lysogenic cycle. Some viruses reproduce using both methods, while others only use the lytic cycle.

Detailed explanation-3: -1: Lytic versus lysogenic cycle: A temperate bacteriophage has both lytic and lysogenic cycles. In the lytic cycle, the phage replicates and lyses the host cell. In the lysogenic cycle, phage DNA is incorporated into the host genome, where it is passed on to subsequent generations.

Detailed explanation-4: -In lysogeny, a virus accesses a host cell but instead of immediately beginning the replication process leading to lysis, enters into a stable state of existence with the host. Phages capable of lysogeny are known as temperate phage or prophage.

Detailed explanation-5: -During the lysogenic cycle, the virus genome is reversibly integrated into the host chromosomes or replicates as a plasmid (or episome) in such a way that it does not lead to virus progeny production.
