Multiple Choice
Which of the following is required to maintain a lysogenic state in a virus?
A
Immediate production of viral proteins
B
Destruction of the host cell
C
Rapid replication of viral particles
D
Integration of viral DNA into the host genome
Verified step by step guidance
1
Understand the lysogenic cycle: In the lysogenic cycle, the viral DNA integrates into the host cell's genome and remains dormant for a period of time.
Recognize that during the lysogenic state, the virus does not immediately produce viral proteins or destroy the host cell.
Identify that the integration of viral DNA into the host genome is a key characteristic of the lysogenic cycle, allowing the virus to be replicated along with the host cell's DNA during cell division.
Note that rapid replication of viral particles is not a feature of the lysogenic state; instead, the viral DNA is passively replicated as part of the host's genome.
Conclude that the integration of viral DNA into the host genome is essential for maintaining the lysogenic state, as it allows the virus to persist without harming the host cell immediately.
