Detailed explanation-1: -Nucleases are enzymes which break down nucleic acids to free nucleotides. These enzymes are present in the pancreatic juice .

Detailed explanation-2: -Chemical Digestion of Nucleic Acids Pancreatic enzymes called ribonuclease and deoxyribonuclease break down RNA and DNA, respectively, into smaller nucleic acids. These, in turn, are further broken down into nitrogen bases and sugars by small intestine enzymes called nucleases.

Detailed explanation-3: -Nucleases are enzymes which catalyze breakdown of nucleic acids. Depending on the position of nucleotide removed, some nuclease are endonucleases which remove nucleotides from internal positions whereas some nucleases are exonucleases which remove nucleotides from an external location.
