DNA microarrays consist of an arrayed series of thousands of microscopic spots of DNA which allow comparisons between two samples of RNA or DNA (target samples), which can provide data on relative gene expression levels (in the case of RNA) or gene copy number (for DNA). The data obtained from two-color DNA microarrays come in the form of fluorescent Red (Cy5) and Green (Cy3) dye intensities. One-color oligonucleotide arrays use only a single fluorescent dye.
