1. Attachment - Virus attaches to the cell wall at a receptor site
2. Entry - The cell wall is weakened by the viral enzymes, and the deoxyribonucleic acid (DNA) of the virus is injected into the host cell.
3. Replication - The DNA of the host cell is inactivated, and the viral DNA takes over making viral proteins and viral nucleic acid.
4. Assembly - Viral coats of protein (capsids) are assembled with the nucleic acids filling the cell with new virus particles.
5. Release - Enzymes dissolve the host cell membrane from within. THe cell then bursts open (cell lysis) and the newly formed virus particles are released, free to infect other bacterial cells.
