Two Japanese researchers find a way to sequence DNA using transistors. In this sequencing process, electrodes called door electrodes are joined by DNA fillets. The chips thus constructed are introduced into a soup with DNA polymerase and nucleotides. Polymerase binds the nucleotides negatively charged to DNA xerox, causing an electrical impulse. The door electrode transports the impulse to a transistor and the computer directly writes the DNA sequence. By this method, DNA sequencing is more economical and can be performed at greater speed.
