DNA. Computer illustration of part of a molecule of beta DNA (deoxyribonucleic acid),the genetic material found in all living cells. Beta DNA spirals clockwise when viewed from above. The DNA is seen unravelled at lower left. DNA encodes and controls all the hereditary traits of living organisms. It consists of two strands wound around each other in a double helix. The strands each have a sugar-phosphate backbone (purple) connected by paired nucleotide bases (yellow,green,brown & blue). It is the sequence of these four types of bases which determines the unique genetic code of an individual | |
