Question 15 • Biology - SC3209 IC

Which best describes the lysogenic cycle?

Answer
A
A person who is infected with the herpes virus may develop a cold sore when the virus is in the lysogenic cycle.
B
The lysogenic cycle occurs mainly in extremely infectious diseases that rapidly cause infection.
C
In the lysogenic cycle, genetic material from the virus and host cells are integrated and are called a provirus.
D
In the lysogenic cycle, virus particles are produced and assembled within the host cell.

Explanation

In the lysogenic cycle, viral genetic material becomes integrated into the host cell’s DNA and can remain there without immediately making new virus particles. The integrated viral DNA is called a provirus (or, in bacteria, a prophage). Choice D describes the lytic cycle, when new virus particles are produced and assembled.
