DNA is a type of biological macromolecule called a nucleic acid.

What kind of macromolecule?

  • DNA (deoxyribonucleic acid) belongs to the macromolecule class known as nucleic acids, one of the four major biological macromolecule groups: carbohydrates, lipids, proteins, and nucleic acids.
  • Nucleic acids are large biomolecules built from smaller units called nucleotides, and DNA is a long chain (polymer) of these nucleotides.
