Which of the following is a restriction endonuclease?

1. Hind II
2. Protease
3. DNase I
4. RNase

Correct answer: Hind II

Hind II is a restriction endonuclease, meaning it recognizes a specific DNA sequence and cleaves the DNA there. Protease digests proteins, DNase I is a nonspecific DNA-degrading enzyme, and RNase digests RNA.
