DNA molecules consist of two anti-parallel chains held together by complementary base pairs that form a double helix.

A DNA Molecule with the Connectivity of a Truncated Octahedron. A truncated octahedron contains six squares and eight hexagons. This is a view down the fourfold axis of one of the squares. Each edge of the truncated octahedron contains two double helical turns of DNA. The molecule contains 14 cyclic strands of DNA. Each face of the octahedron corresponds to a different cyclic strand. In this drawing, each nucleotide is shown with a colored dot corresponding to the backbone, and a white dot…

The DNA is a molecular chain physically located in chromosomes, structures present in the nucleus of cells. Genes are encoded by the DNA and specify how and when to build proteins which then act as molecular machines. These molecular machines interact in complex networks to perform most vital functions in cells. The communities of cells, through complex interactions, then give rise to animals, including human beings.
