Restriction enzyme. A restriction enzyme or restriction endonuclease is an enzyme that cuts DNA at or near specific recognition nucleotide sequences known as restriction sites.
Restriction enzymes are used to cut up DNA into fragments with 'sticky ends'. It allows for the gene of interest to be isolated. A plasmid can then also be cut with the same r â¦ estriction enzyme and the sticky ends are spliced together with DNA ligase.estriction enzymes are used to cut up DNA into fragments with 'sticky ends'.
