Which of the following is a restriction endonuclease?

Solution
The correct option is B HindIII
A restriction endonuclease is an enzyme that cleaves DNA into fragments at or near specific recognition sites within molecules known as restriction sites. Hind III is a restriction endonuclease.
DNase I - is a nuclease that cleaves DNA preferentially at phosphodiester linkages adjacent to a pyrimidine nucleotide, yielding 5'-phosphate-terminated polynucleotides with a free hydroxyl group on position 3', on average producing tetranucleotides.
RNase - Cleaves RNA molecules
Protease - an enzyme that breaks down proteins into smaller polypeptides or single amino acids.
