The monomeric unit of are nucleotides. Nucleic acids are the polymer.
Nucleic acids are one of the macromolecules of life. Examples include ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). These are polymers, which are composed of their monomeric unit, nucleotides. An example of the nucleotide, adenine, is shown below and has three major components: a phosphate group, a sugar, and a nitrogenous base.
Nucleotides are linked together by phosphodiester bonds, shown below, to form their polymers (DNA or RNA).
