The key differences between the lysogenic and lytic cycles can be summarized as follows:
-
Lytic Cycle:
- The host cell is destroyed as the new viral particles are released. This cycle results in cell lysis and death of the host to release the virus.
- Viral proteins are synthesized and assembled rapidly, leading to the immediate production of new viruses.
-
Lysogenic Cycle:
- The virus integrates its DNA into the host's genome, where it can remain dormant for an extended period. The host cell replicates its own DNA along with the viral DNA during cell division, without causing immediate harm to the host.
- Viral proteins are not immediately synthesized; instead, the viral DNA is passed on to daughter cells.
In summary, the lytic cycle destroys the host and produces new viruses quickly, while the lysogenic cycle involves integration and dormancy of the viral DNA in the host genome without immediate viral production or destruction of the host cell.
