Question

Nucleic acid is fragmented by enzyme

• A. polymerases
• B. ligases
• C. nucleases
• D. proteases

Answer 1

The correct option is C nucleases

Nucleic acids are naturally occurring chemical compounds made up of nucleotides. They are the primary information carriers in a cell. Examples include DNA and RNA.

Ligases are enzymes that catalyze the formation of phosphodiester bonds between DNA molecules resulting in the joining of two DNA molecules.

Proteases are enzymes that digest polypeptides into amino acids.

Any enzyme that helps in the cleavage of nucleic acids is called nucleases. They are able to cut the DNA into fragments by breaking the phosphodiester bonds. These are of two types based on their action: endonucleases and exonucleases.

Polymerase enzymes allow the formation of a long chain of nucleic acids using nucleotides by creating phosphodiester bonds. These enzymes help in the replication or synthesis of nucleic acids. Examples include DNA polymerases and RNA polymerases.

Hence the correct option is
c. nucleases
