Deoxyribonucleic Acid (DNA)

Science / Genetics / Deoxyribonucleic Acid (DNA): The molecule that encodes genetic information. Dna is a double-stranded molecule held together by weak bonds between base pairs of nucleotides. The four nucleotides in dna contain the bases adenine (a), guanine (g), cytosine (c), and thymine (t). In nature, base pairs form only between a and t and between g and c: thus the base sequence of each single strand can be deduced from that of its partner.
