Nucleic acids are built from nucleotide monomers; which examples represent this macromolecule?

• A. Lipid monomers
• B. Amino acids
• C. Monosaccharides
• D. DNA and RNA

Answer: (C)

Nucleic acids are long polymers built from nucleotide monomers, each containing a sugar, a phosphate group, and a nitrogenous base. The two main nucleic acids in biology are DNA and RNA, which are chains of nucleotides and carry genetic information. So DNA and RNA are the examples that represent this macromolecule. Lipid monomers form lipids, amino acids form proteins, and monosaccharides form carbohydrates, so those choices correspond to other kinds of macromolecules.
