DNA. Computer-digitised illustration of the double helix molecule of DNA (deoxyribonucleic acid). The coloured spheres represent the atoms in the DNA molecule. DNA is fundamental to life on Earth,apart from some micro-organisms and viruses that have instead a related compound called RNA (ribo- nucleic acid). DNA carries all the instructions needed to build an organism in a chemical code spelt out along the rungs of the helix. Specific portions of the code (genes) are transcribed by cells into proteins. These proteins control how the cell develops,behaves and communicates with inheritance between different generations | |
