  • An early DNA fingerprint showing DNA patterns from a mother (lanes 2 and 8) and her four children (adjacent lanes to the right). Lane 1 is an unrelated person. The two sets of lanes show the fingerprints reveled with two different probes that detect different types of repeated sequences.
  • DNA sequencing. This method of DNA sequencing is called di-deoxy sequencing. It is used to determine the order of bases (A,C,G and T) in a piece of DNA using radioactively-labelled modified nucleotides. They are then separated by electrophoresis in a polyacrylamide gel and detected on x-ray film by a process called autoradiography.
  • The first DNA fingerprint. The first three lanes contain DNA from a woman, her mother and her father respectively. Lanes 4 - 11 contain DNA from assorted other species including mouse, baboon, lemur, cow, grey seal and tobacco (last lane). The DNA probe used in this experiment detected tandomly repeated short stretches of DNA called minisatellites whose length varies between individuals.
  • The cochlea is a vital part of our ear, allowing us to detect a wide range of frequencies of sound. This is a picture showing the characteristic snail shell structure of the cochlea in the inner ear, captured on a high-resolution electron microscope. The bone usually covering the cochlea has been removed to open up a window into the hidden world of hearing.
