Definition
A restriction enzyme is an endonuclease that binds and cuts double-stranded DNA at a specific nucleotide sequence. Some restriction enzymes cut both strands, generating blunt ends whereas others generate sticky ends. Restriction combined with DNA modification, which impede the cutting of the DNA, is a protection system against the introduction of foreign DNA sequences into prokaryotic systems. These enzymes have been instrumental in the development of cloning and genetic engineering techniques.
