The main differences between the lysogenic and lytic cycles are as follows:
1. Host cell destruction: In the lytic cycle, the host cell is destroyed when new viral particles are released, while in the lysogenic cycle, the host cell is not immediately destroyed.
2. Synthesis of viral proteins: Viral proteins are synthesized during the lysogenic cycle, but not during the lytic cycle.
3. Host cell DNA replication: The host cell does not copy its own DNA during the lytic cycle, but during the lysogenic cycle, the viral DNA integrates with the host cell's DNA and gets replicated along with it.
4. Injection of viral DNA: In the lysogenic cycle, the virus injects its DNA into the host cell, integrating with the host cell's DNA. This does not occur in the lytic cycle.
In summary, the lysogenic cycle is characterized by the integration of viral DNA into the host cell's DNA, without immediate cell destruction, and the synthesis of viral proteins. On the other hand, the lytic cycle involves immediate host cell destruction, replication of viral DNA, and the absence of viral protein synthesis.
