Stages in Lytic Infection:

1. The virus injects DNA into a bacterium.
2. Viral genes are transcribed by the host cell.
3. The bacterium makes new viral proteins and nucleic acids.
4. The proteins and nucleic acids assemble into new viruses.
5. Viral enzymes lyse the bacterium’s cell wall. The new viruses escape and infect other bacterial cells.

Stages in Lysogenic Infection:

1. The virus injects DNA into a bacterium.
2. The viral DNA inserts itself into the bacterial chromosome, where it is called a prophage.
3. The prophage may replicate with the bacterium for many generations.
4. The prophage can exit the bacterial chromosome and enter a lytic cycle.
5. The bacterium makes new viral proteins and nucleic acids.
6. The proteins and nucleic acids assemble into new viruses.
7. Viral enzymes lyse the bacterium’s cell wall. The new viruses escape and infect other bacterial cells.
