In the lysogenic cycle, _____.

• A. the virus produces toxins that kill the host cell
• B. the host cell is immediately lysed to release new viruses
• C. the viral RNA is directly translated into viral proteins
• D. the viral DNA integrates into the host genome and replicates along with it

Answer: (D)

Verified step by step guidance

1. Understand the lysogenic cycle as one of the two main viral replication cycles, the other being the lytic cycle.
2. Recognize that in the lysogenic cycle, the viral DNA integrates into the host cell's genome rather than immediately producing new viruses.
3. Know that once integrated, the viral DNA (called a prophage in bacteriophages) replicates along with the host cell's DNA during cell division.
4. Note that during this phase, the virus does not kill the host cell or produce toxins; instead, it remains dormant within the host genome.
5. Conclude that the lysogenic cycle allows the virus to persist in the host without causing immediate lysis, distinguishing it from the lytic cycle where the host cell is lysed to release new viruses.
