Unformatted text preview: 4.) Cell explodes cell lyses viruses are released Lysogenic Cycle (invasion of a bacterial cell) 1.) Hook on host cell (attachment) 2.) Injects nucleic acid into the cell 3.) Infected cell undergoes mitosis (bacterial cell replication) 4.) Colony of infected bacteria sometimes occurs 5.) Cells undergo stress lytic cycle occurs (activation event is the stress and induces the lytic cycle) [conditions can cause the lysogenic phage to witch to the lytic cycle]...
