Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When a virus injects its DNA and it merges with the host cell’s DNA, which cycle is occurring?
A
Mitosis
B
Meiosis
C
Lytic Cycle
D
Lysogenic Cycle
Explanation: 

Detailed explanation-1: -The lysogenic cycle: The phage infects a bacterium and inserts its DNA into the bacterial chromosome, allowing the phage DNA (now called a prophage) to be copied and passed on along with the cell’s own DNA.

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.

Detailed explanation-3: -In the lysogenic cycle, the viral genome gets inserted into the host genome. Viruses which can perform both lytic and lysogenic cycles are called temperature viruses.
