restriction enzyme

n.
Any of a group of enzymes that catalyze the cleavage of DNA at specific sites to produce discrete fragments, used especially in genetic engineering. Also called restriction endonuclease.

restriction enzyme

n
(Biochemistry) any of several enzymes produced by bacteria as a defence against viral infection and commonly used to cut DNA for genetic manipulation or diagnosis

ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.restriction enzyme - any of the enzymes that cut nucleic acid at specific restriction sites and produce restriction fragments; obtained from bacteria (where they cripple viral invaders); used in recombinant DNA technology
endonuclease - a nuclease that cleaves nucleic acids at interior bonds and so produces fragments of various sizes
