Nucleic acids are:

Explanation:
Nucleic acids are polymers of nucleotides, with DNA and RNA as the two main types. Each nucleotide contains a sugar, a phosphate group, and a nitrogenous base, and nucleotides are linked by phosphodiester bonds to form long chains. This polymeric structure carries genetic information—the sequence of bases encodes instructions for building and regulating organisms. Lipids, proteins, and carbohydrates are other biomolecule classes built from different building blocks and do not consist of nucleotides, which is why they are not nucleic acids.
