Condensation of DNA, illustration
Condensation of DNA (deoxyribonucleic acid), illustration. At left the DNA double helix is tightly coiled around histone proteins (yellow). The histones are then tightly packaged together in groups of eight to form nucleosomes that are then coiled together and further packaged into chromosomes (right). Each human cell contains 23 pairs of chromosomes, which contain all the body's genetic information.
