en·do·nu·cle·ase

 (ĕn′dō-no͞o′klē-ās′, -āz′, -nyo͞o′-)
n.
Any of a group of enzymes that catalyze the hydrolysis of bonds between nucleotides in the interior of a DNA or RNA molecule.

endonuclease

(ˌɛndəʊˈnjuːklɪˌeɪz)
n
(Biochemistry) an enzyme that is responsible for scission of a nucleic acid chain, the action of which is not confined to the terminal nucleotide. Compare exonuclease

(ˌɛn doʊˈnu kliˌeɪs, -ˌeɪz, -ˈnyu-)

n.
any of a group of enzymes that degrade DNA or RNA molecules by breaking linkages within the polynucleotide chains.

Noun1.endonuclease - a nuclease that cleaves nucleic acids at interior bonds and so produces fragments of various sizes
nuclease - general term for enzymes that catalyze the hydrolysis of nucleic acid by cleaving chains of nucleotides into smaller units
restriction endonuclease, restriction enzyme, restriction nuclease - 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
