Hind II are restriction endonuclease because they cleave DNA at specific sequence within DNA strand. They only cut DNA not RNA. Correct option is D A restriction enzyme or restriction endonuclease is an enzyme that cleaves DNA into fragments at or near specific recognition sites within the molecule known as restriction sites.
