DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are nucleic acids composed of nucleotides (sugar, phosphate, nitrogenous base). DNA forms a double helix with complementary base pairing (A–T, C–G). RNA is typically single-stranded, but can form complex secondary structures. They carry genetic information (DNA) and mediate protein synthesis (RNA), underpinning all cellular processes and heredity.
