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).
