Nucleic acid is fragmented by enzyme

Options

(a) Ligases
(b) Proteases
(c) Nucleases
(d) Polymerases

Correct Answer:

Nucleases

Explanation:

A nuclease (also archaically known as nucleodepolymerase or polynucleotidase) is an enzyme capable of cleaving the phospodiester bonds between monomers of nucleic acids. Nucleases variously effect single and double stranded breaks in their target molecules. In living organisms, they are essential machinery for many aspects of DNA repair. Defects in certain nucleases can cause genetic instability or immunodeficiency. Nucleases are also extensively used in molecular cloning.
