All GeneChip microarrays take advantage of thenatural chemical attraction between DNAmolecules. There are only four molecules, or“bases”, in every DNA chain: adenine (A),guanine (G), thymine (T) and cytosine (C).These four molecules partner: C partners with Gand T partners with A. Pairing is a natural statefor DNA and if you pulled the double helix apart,it would inevitably move back together, like twolong chains of magnets that are attracted toeach other.
