A molecule that builds itself out of itself. Now engraved into silver to wear daily. The Science Behind DNA DNA is a double helix of two antiparallel strands joined by base pairing: adenine to thymine, guanine to cytosine. The 3. 4 nanometre distance between base pairs determines the helix pitch (10. 5
