DNA molecule. Computer graphic of a molecule of Deoxyribonucleic Acid (DNA). DNA encodes an organism's genetic information. The spherical atoms are colour-coded: phosphorus is orange,oxygen is red,carbon is dark blue,and nitrogen is light blue. DNA is a spiral helix made up of two strands of sugar-phosphate groups which twist around each other. These are connected in the centre by nitrogen-containing nucleotides. The sequence of paired nucleotides makes up the genetic code. This DNA was modelled on DNA produced by the HIV virus after it infects a human cell to make more viruses,causing AIDS.
