Verified step by step guidance1
Understand that biological macromolecules are large molecules essential for life, including carbohydrates, proteins, lipids, and nucleic acids.
Recall that DNA (deoxyribonucleic acid) is composed of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.
Recognize that nucleotides are the building blocks of nucleic acids, making DNA a type of nucleic acid.
Differentiate DNA from carbohydrates (which are made of sugar units), proteins (made of amino acids), and lipids (made of fatty acids and glycerol).
Conclude that DNA is classified as a nucleic acid because of its nucleotide composition and role in storing genetic information.
