(PhysOrg.com) -- The human genome contains some 3 billion base pairs that are tightly compacted into the nucleus of each cell. If a DNA strand were the thickness of a human hair, the entire human genome would be crammed into a space the size of a softball, but if it were unraveled and all the strands lined up, they would stretch from Ithaca, N.Y., to Boston.
