DNA. Computer illustration of part of a molecule of beta DNA (deoxyribonucleic acid),the genetic material found in all living cells,in front of a genetic sequence. Beta DNA spirals clockwise when viewed from above. The spherical atoms are colour- coded: oxygen (red),phosphorus (orange),carbon (white),hydrogen (light blue) and nitrogen (dark blue). DNA encodes and transmits the hereditary characteristics of living organisms. It consists of two strands,each having a sugar-phosphate backbone linked by paired nucleotide bases to form a double helix. The sequence of these four bases,cytosine (C),guanine (G),thymine (T) and adenine (A),determines each person's unique genetic code | |
