A) Lipase
B) Exonuclease
C) Endonuclease
D) Protease
Correct Answer: C
Solution :
DNAase (or deoxyribonuclease) or simply nuclease is an enzyme which breaks down DNA by hydrolysis of the phosphodiester bonds of its sugar-phosphate back bone. Depending on the position of hydrolyzing phosphodiester bonds, nucleases are of two types: (i) Endonucleases (ii) Exonucleases. Endonucleases hydrolyse internal phosphodiester bonds in a polynucleotide chain (.i.e., DNA). While exonucleases hydrolyse terminal phosphodiester bonds in a polynucleotide chain (.i.e., DNA).
