Leonard Adleman, a mathematician at the University of Southern California, combined microscopic bits of DNA to calculate a well-known computer problem. A DNA computer processes each step comparatively slowly, but it can work on billions of sites at once in a cell or a test tube. The standard computer problem that Adleman tackled in his lab is one that seeks a route connecting seven cities, some of which have no direct connections between them, in such a way that a hypothetical traveller arrives at each city only once without backtracking. He solved this puzzle by treating the chemical units of DNA as computing symbols, then assigning a series of symbols to each "city." He then used DNAs natural affinity to join its strands together to create possible city-to-city sequences. In a test tube, very short bits of DNA zipped on to other bits, until all possible routes to the seven cities were assembled very rapidly. This sorting of codes serves as a type of computation even though the DNA was doing nothing unusual. 1, record 1, English, - DNA%20computer

Vers l'ordinateur à ADN [...] Face à un bogue, les puces déclencheront forcément la bonne réaction de la même façon que notre système immunitaire s'adapte à une nouvelle maladie. Du coup, certains informaticiens se prennent carrément à rêver au «DNA computing», un ordinateur constitué en partie de «briques» d'ADN. 1, record 1, French, - ordinateur%20%C3%A0%20ADN
