− | Today you will use one tool, a DNA microarray, to simultaneously examine the expression of many genes. DNA microarrays are slides with DNA sequences spotted in a known order on the surface. The spots of DNA, each one smaller than the period at the end of this sentence, are placed on the slide surface with robotic arms or built one base at a time with photolithography. Each spot of DNA gets a unique address on the slide surface, and the identity and location of each spot get stored in the computerized | + | Today you will use one tool, a DNA microarray, to simultaneously examine the expression of many genes.
