DNA is an example of a macromolecule, i.e. a large molecule with a special shape, which is built up from many smaller parts called sub-units. If you could magnify part of a nucleus, you would see the DNA molecule looking like a twisted rope ladder - a double helix. The two strands forming the sides of the ladder give it a strong yet flexible structure, which does not vary along its length.

These parts are made up of sections called bases, which fit together in pairs
