Caption

DNA packaging. Computer artwork showing how DNA (deoxyribonucleic acid) is packaged within a cell nucleus. A double strand of DNA is at bottom. Each strand consists of a sugar-phosphate backbone (horizontal blue line) attached to nucleotide bases. There are four nucleotide bases. The two strands twist into a double helix (lower right). The DNA double helix is tightly coiled around histone proteins (red). Eight histone proteins are tightly packaged together to form a nucleosome (centre left), which is further packaged into chromosomes (top left). In each human cell (top right) are 23 pairs of chromosomes, which contain all the body's genetic information.
