Verified step by step guidance1
Recall the four main types of biological macromolecules: proteins, lipids, carbohydrates, and nucleic acids.
Understand that DNA (deoxyribonucleic acid) is composed of nucleotide monomers, which consist of a sugar, phosphate group, and nitrogenous base.
Recognize that nucleotides are the building blocks of nucleic acids, making DNA a nucleic acid macromolecule.
Differentiate DNA from proteins (made of amino acids), lipids (fats and oils), and carbohydrates (sugars and starches) based on its structure and function.
Conclude that DNA is classified as a nucleic acid because it stores genetic information and is made up of nucleotide chains.
