What is the lytic life cycle?
First, during the first 22 minutes, it is the latent period. There is no change in the nmber of infected cells during the first 22 minutes. After 22 minutes, the number of infected cells starts to increases, showing that lysis is occurring, and that new bacteriophages are infecting others.
The initial event is attachment of the bacteriophage to a receptor protein on the outside of the bacterium. Then comes the latent period, a period of frenzied activity within the cell in which DNA, RNA, and protein stops and transcription of the bacteriophage genome begins. Within five minutes, the bacterial DNA molecule has been broken down and the resulting mucleotides are being utilized in replication of the T4 genome. After 12 minutes, new bacteriophage capsid proteins start to appear and the first complete bacteriophage particles are assembled. At the end of the latent period, the cell bursts and the new bacteriophages are released.
