Which of the following is a characteristic of the lysogenic cycle in viruses?

• A. Immediate destruction of the host cell
• B. Rapid production of new viral particles
• C. Release of viruses through budding
• D. Integration of viral DNA into the host genome

Answer: (D)

Verified step by step guidance

1. Understand the lysogenic cycle: The lysogenic cycle is one of the two cycles of viral reproduction, the other being the lytic cycle. In the lysogenic cycle, the virus integrates its genetic material into the host cell's DNA, allowing it to replicate along with the host cell without causing immediate harm.
2. Differentiate between the lysogenic and lytic cycles: In the lytic cycle, the virus takes over the host cell's machinery to produce new viral particles, leading to the destruction of the host cell. In contrast, the lysogenic cycle involves the integration of viral DNA into the host genome, where it can remain dormant for a period.
3. Identify the key characteristic of the lysogenic cycle: The integration of viral DNA into the host genome is a defining feature of the lysogenic cycle. This allows the viral DNA to be replicated passively as the host cell divides.
4. Consider the options provided: Immediate destruction of the host cell and rapid production of new viral particles are characteristics of the lytic cycle, not the lysogenic cycle. Release of viruses through budding is a process seen in some viruses but is not specific to the lysogenic cycle.
5. Conclude with the correct characteristic: The correct answer is 'Integration of viral DNA into the host genome,' as this is the primary feature that distinguishes the lysogenic cycle from the lytic cycle.
