Begin by understanding the basic building blocks of each type of biological macromolecule. Nucleotides are the monomers that make up nucleic acids.
Recall that nucleic acids are polymers composed of long chains of nucleotides. The two main types of nucleic acids are DNA and RNA.
Consider the structure of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base. These components link together to form the backbone of nucleic acids.
Differentiate nucleic acids from other macromolecules: Proteins are made of amino acids, carbohydrates are made of sugar units, and lipids are composed of fatty acids and glycerol.
Conclude that the polymer composed of many nucleotides is a nucleic acid, as it is the only macromolecule formed from nucleotide monomers.
