DNA, RNA and genes

Labelled comparison of DNA double helix and single-stranded RNA showing sugar-phosphate backbone, deoxyribose, ribose, base pairs, hydrogen bonds and strand direction DNA stores genetic information in genes, which are sequences of bases that code for a polypeptide or a functional RNA. Proteins made from these instructions act as enzymes, receptors, channels or structural molecules.
