  1. recognize proteins on the surface of the phage and secrete enzymes that digest the phage.

  2. recognize proteins on the surface of the phage and secrete proteins that block the binding of the phage.

  3. integrate fragments from the phage DNA in their own chromosomes and target for destruction any DNA that contains the same fragments in the future.
