Genetic research. Computer artwork of an example of genetic biotechnology, the DNA Biochip (along left), and a molecule of DNA (deoxyribonucleic acid, right). The DNA Biochip allows cheap and rapid simultaneous analyses, such as identifying infectious organisms in samples of blood. It consists of a glass slide holding dots of DNA (red, green, blue). Each dot contains a different piece of DNA, designed to bind to a specific gene on the DNA of the test sample. The Biochip is then scanned by a laser, which highlights the dots on which a reaction has taken place. The known distribution of the DNA on the chip allows the results to be used to identify the sample.
