Guida verificata passo dopo passo1
Recall the four major types of biological macromolecules: carbohydrates, lipids, proteins, and nucleic acids.
Understand that DNA (deoxyribonucleic acid) is composed of nucleotide monomers, which include a sugar, phosphate group, and nitrogenous base.
Recognize that molecules made up of nucleotides are classified as nucleic acids.
Eliminate other options: lipids are fats and oils, proteins are made of amino acids, and carbohydrates are sugars and polysaccharides.
Conclude that DNA is classified as a nucleic acid based on its molecular structure and function.
