WebIntroduction. Special enzymes termed restriction enzymes have been discovered in many different bacteria and other single-celled organisms. These restriction enzymes are able to scan along a length of DNA looking for a particular sequence of bases that they recognize. This recognition site or sequence is generally from 4 to 6 base pairs in length.
