Restriction enzymes are present in all types of bacteria. They are used as a defense mechanism against viruses (bacteriophages). Restriction enzymes cut a sequence of the bacteria’s DNA between two alternate base pairs and then bind to the major groove of one of the newly broken bases. The exact position of the break in the DNA sequence depends on the type of bacteria and enzyme.References:”Microbiology: Principles and Explorations”; Jacquelyn G.
