About it
DNA is the long molecule that carries the instructions for building and running a living thing. It is shaped like a twisted ladder, a double helix: two strands wind around each other, joined by pairs of bases, A with T and C with G, like the rungs.
Tap it and it unzips almost to the bottom, the bases lighting up in pairs as it opens, then zips back up. A cell unzips its DNA like this to copy it. In 1953 scientists worked out its shape, helped by Rosalind Franklin's X-ray pictures. The DNA in a typical human cell with a nucleus would stretch about 2 meters if pulled straight. Partner sets the matching strand's color.
