describe the structure of dna molecules.
user
dna molecules have a double helix structure, with two strands of deoxyribonucleic acid (dna) wound around each other. each strand consists of four nitrogenous bases; adenine, thymine, guanine, and cytosine, paired in a specific order. the complementary pairing of nitrogenous bases structurally stabilizes the double helix, and forms the basis for genetic information storage, replication, and expression.
