Verified step by step guidance

Understand the definition of a polymer: A polymer is a large molecule composed of repeating subunits called monomers. In this case, the monomers are nucleotides.

Recall the structure of a nucleotide: A nucleotide consists of three components: a nitrogenous base, a pentose sugar (ribose or deoxyribose), and a phosphate group.

Identify the biological macromolecules that are composed of nucleotide monomers: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are polymers of nucleotides, where the nucleotides are linked by phosphodiester bonds.

Eliminate the incorrect options: Proteins are polymers of amino acids, lipids are not polymers, fatty acids are components of lipids, and polysaccharides are polymers of monosaccharides (sugars).

Conclude that DNA and RNA are the correct examples of polymers of nucleotides, as they are composed of long chains of nucleotide monomers linked together.
