Which term describes the building block of nucleic acids?

Explanation:
Nucleic acids are polymers built from repeating units called nucleotides. Each nucleotide contains a sugar, a phosphate group, and a nitrogenous base, and linkages between the sugars and phosphates form the backbone of the DNA or RNA strand. Because a nucleotide is the specific unit that makes up nucleic acids, it is the correct term for the building block. A monomer is a general term for the single unit that makes up any polymer, so it’s related but not as specific to nucleic acids. A monosaccharide is the building block of carbohydrates, and an amino acid is the building block of proteins.
