Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During which reproductive cycle do viruses turn host cells into virus making machines?
A
Lytic Cycle
B
Lysogenic Cycle
C
Passive Cycle
D
Active Cycle
Explanation: 

Detailed explanation-1: -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-2: -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-3: -Replication: The virus takes over the cell’s metabolism, causing the creation of new proteins and nucleic acids by the host cell’s organelles. Assembly: Proteins and nucleic acids are assembled into new viruses.

Detailed explanation-4: -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-5: -The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. Typically, viruses can undergo two types of DNA replication: the lysogenic cycle or the lytic cycle. In the lysogenic cycle, the DNA is only replicated, not translated into proteins.
