1)  The  virus  binds  to  the bacterial host cell surface by the tail
   fibers.
   2)  The tail sheath contracts and causes the central core to penetrate
   the cell wall.
   3)  The  protein  coat  remains  outside  the  host while viral DNA is
   injected; host DNA is degraded.
   4)  Viral  molecules are synthesized using host resources; assembly of
   progeny phages from components begins.
   5)  A  phage  enzyme  (lysozyme)  ruptures (lyses) the cell, releasing
   progeny phages and completing the lytic cycle.
