DNA nucleotides, computer artwork. Section of a double stranded DNA (deoxyribonucleic acid) molecule showing the molecular structure of adenine (A) and thymine (T) bonded together. DNA is composed of two strands twisted into a double helix. Each strand consists of a sugar-phosphate backbone (far left and right) attached to nucleotide bases (centre left and right). There are four bases: adenine, thymine, guanine and cytosine, which join together with hydrogen bonds (centre). Thymine always pairswith adenine, and guanine always with cytosine.
