Step 1: Absorption
Attachment of absorption of tail fibres of the phages on to a specific receptor site on the bacterial cell wall.
Step 2: Injection
Injection of viral genome into the host through the hollow tubes of the tail.
Step 3: Protein synthesis
Inside the host, the viral genome directs the synthesis of viral proteins using the machinery of the host. Viral genome generally encodes for some enzymes and coat proteins.
Step 4: Viral genome synthesis
Viral genome replicates inside the host making several copies of it self.
Step 5 & 6: Packaging and release
The viral genome gets packed inside the protein coat.
These intact mature infectious particles are called virions. The crowding of virions inside the host ultimately cause cell lysis and liberation of mature viral particles – about 200 mature phages are liberated.
