Dear student

Restriction endonuclease protects a bacteria from the attack of
bacteriophages There are restriction sites present in the genome of
bacteriophage, which can be cleaved by the restriction endonuclease
of bacteria This destroys the DNA of bacteriophage, as a result of
which bacteriophage will not be able to kill a bacterial cell
