Study Notes
Lysogenic Cycle Steps
- Attachment and Injection: A bacteriophage attaches to a host cell and injects its DNA into the cell.
- Prophage Formation: The injected viral DNA integrates with the host cell's DNA, forming a structure known as a prophage.
- Replication of Prophage: The prophage replicates alongside the host cell's DNA during cell division.
- Colony Formation: Repeated cell divisions lead to the establishment of a bacterial colony that is infected with the prophage.
-
Final Outcomes: The prophage can either:
- Exit the host cell's DNA and shift to the lytic cycle, leading to cell lysis and release of new virions.
- Remain dormant within the host cell, maintaining a non-lytic relationship.
