Which of the following is a endonuclease?
(b) DNase I
(c) RNase restriction
(d) Hind II
(d) I-Iind II is a restriction endonuclease. Restriction endonucleases are enzymes used for cutting of
DNA at specific locations.
Hind II was the first restriction endonuclease isolated by Smith Wilcox and Kelley in 1968. It was
found that it always cut DNA molecules at a particular point by recognising a specific sequence of six
