Verified step by step guidance1
Recall the four major types of biomolecules: carbohydrates, proteins, lipids, and nucleic acids.
Understand that DNA (deoxyribonucleic acid) carries genetic information and is composed of nucleotides.
Recognize that nucleotides are the building blocks of nucleic acids, which include DNA and RNA.
Eliminate carbohydrates, proteins, and lipids as they serve different biological functions (energy storage, structural components, enzymes, and membranes).
Conclude that DNA is classified as a nucleic acid because it is made up of nucleotide monomers and stores genetic information.
