1. Attachment: The virus attaches to the host cell on a specific receptor site. THE LYSOGENIC CYCLE

2. Injection: The virus injects it’s nucleic acid into the host cell.

3. Integration: The viral nucleic acid becomes integrated into the host cell’s DNA. This is called a PROVIRUS.

4. Hiding: As the host cell’s DNA replicates during the cell cycle, so does the integrated provirus. The new daughter cells also contain the viral nucleic acid.

5. Enters the Lytic Cycle: At any given moment, the provirus leaves the host cell’s DNA and takes over the cell’s metabolic activities.

6. Assembly: The viral nucleic acid forces the cell to make more viral particles.

7. Lysis: The virus particles burst out of the host cell, killing the cell.

8. THE LYTIC CYCLE Attachment: The virus attaches to a host cell on a specific receptor site.

9. Injection: The virus injects it’s nucleic acid into the host cell.

10. Take over: The viral nucleic acid takes over the host cell’s metabolic activities.

11. Assembly: The viral nucleic acid forces the cell to make more viral particles.

12. Lysis: The virus particles burst out of the host cell, killing the cell.
