Which term describes viruses that can remain dormant in the host genome and later reactivate?

• A. Lytic cycle
• B. Budding cycle
• C. Lysogenic cycle
• D. Persistent cycle

Answer: (C)

The lysogenic cycle describes viruses that can stay dormant by integrating their genome into the host’s DNA and being replicated with the host cell without making new viruses. This quiet state can persist through many cell divisions, and later, under certain conditions, the viral genome can reactivate and switch to the lytic cycle to produce new virions and lyse the cell. The lytic cycle is the opposite: immediate replication and host destruction. The budding cycle refers to how some enveloped viruses exit the cell, not dormancy. The persistent cycle isn’t the standard term for a genome that hides in the host and can reactivate later. So, the term that fits dormancy with potential reactivation is lysogenic cycle.
