Understand the concept of viral replication cycles: Viruses can replicate through different cycles, primarily the lytic and lysogenic cycles.
In the lytic cycle, the virus takes over the host cell's machinery to replicate its genetic material and produce new virus particles, eventually causing the host cell to burst (lyse) and release the new viruses.
In the lysogenic cycle, the viral DNA integrates into the host cell's genome and becomes a prophage. This viral DNA can remain dormant or latent within the host's genome for an extended period without causing immediate harm to the host.
During the lysogenic cycle, the viral genes are replicated along with the host cell's DNA during cell division, allowing the virus to persist in the host without being detected.
The lysogenic cycle is characterized by the latency of viral genes, meaning they are present but not actively causing the production of new viruses until triggered to enter the lytic cycle.
