A restriction enzyme is used for various purposes as far as the DNA is concerned. For example, it is used for the purposes of cutting DNA at a point or location near the restriction site. Restriction sites refer to a specific nucleotide sequence found in a DNA molecule. The restriction site is used for the purposes of recognizing a particular DNA molecule.3Â The restriction enzymes are commonly found in bacteria and archaea species. To date, scholars and researchers working in this field have discovered and documented over 3000 restriction enzymes. Advances in biotechnology have enabled scientists around the world to synthesize over 600 enzymes in laboratories under a controlled environment. Such technological advances have made the commercial production of the enzymes a viable venture. The enzymes form part of the organismâ€™s defense mechanism, helping it wage war against viruses attempting to invade it. The process through which the restrictive enzyme selectively cuts up a foreign DNA molecule is referred to as restriction.
