Conceptual computer artwork of DNA fingerprinting used to prove family relationships. The illustration is based on a sequence of bases in a fragment of DNA (deoxyribonucleic acid), part of an autoradiograph of bands of DNA produced by the technique of electrophoresis. The pattern of these DNA bands is unique to each individual, but some bands are shared by related people, such as a parent & child. DNA fingerprints can be used to prove conclusively whether people are related. This illustration shows the sequence graphics rearranged to display the letters DNA.
