Multiple Choice

Deoxyribonucleic acid and ribonucleic acid belong to

This item is testing which class DNA and RNA belong to. DNA and RNA are nucleic acids, a type of macromolecule built from nucleotide units. They store and transmit genetic information and direct protein synthesis, which is the hallmark of nucleic acids. Their structure features a sugar-phosphate backbone with nitrogenous bases that encode genetic information. This distinguishes them from proteins (made of amino acids with diverse roles like enzymes and structural components), carbohydrates (primarily energy sources and structural support), and lipids (nonpolar molecules forming membranes and energy storage). So, DNA and RNA belong to nucleic acids.
