Understand the question is asking about the classification of DNA and RNA, which are biological macromolecules.
Recall that DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are molecules that store and transmit genetic information.
Identify the four main types of biological macromolecules: carbohydrates (including monosaccharides), lipids (including phospholipids), proteins, and nucleic acids.
Recognize that DNA and RNA belong to the category of nucleic acids, which are polymers made up of nucleotide monomers.
Conclude that DNA and RNA are both types of nucleic acids, not monosaccharides, proteins, or phospholipids.
