Caption: Forensic science laboratory using DNA fingerprinting. Overhead view of laboratory technicians checking DNA autoradiographs (autorads). These are produced by labelling the DNA fragments in an electrophoresis gel with a radioactive marker chemical. The gel is then placed on an piece of X-ray film, the radiation from the marker leaves a dark patch, representing each fragment, on the film after development. Comparison of autorads from two samples of DNA is the method by which a correlation may be made - so-called DNA fingerprinting. Photographed at Cellmark Diagnostics, a commercial laboratory at Oxford, England.
