WebHow does array CGH work? A microarray works by exploiting the ability of a DNA molecule (or strand) to bind specifically to, or hybridise to, another DNA molecule (strand). The DNA in our cells is arranged as a double helix (see Figure 2) in which the two strands of DNA are bound (‘paired’) together by bonds between the base pairs (bps). WebMicroarrays Made Simple: “DNA Chips” Paper Activity A DNA microarray (DNA chip) is an ordered array of different known sequences of DNA (~20-70 bases long).
