The diameter of a metaphase chromosome is about 1400 nm, whereas that of the DNA double helix is 2 nm. This means that DNA is coiled into a structure with a diameter 700 times larger than itself. The diameter of a human hair is about 80 micrometers (0.003 inch). If a human hair were coiled into a structure with a diameter 700 times larger than itself, the diameter of the coiled human hair would approximate that of a: telephone pole (about 18 inches). trash can (about 36 inches). spaghetti noodle (about 0.1 inch). soda can (about 2 inches). pencil (about 0.3 inch).
