Making Sense of the Data

< Previous SectionNext Section >

Microarrays make it possible to compare the relative expression of thousands of genes in cancer and normal cells by measuring the intensity and color of the fluorescence of each spot. A computer program can then analyze the data and make precise measurements of genes expressed at high levels and low levels. Most microarray studies now include "cluster analysis," which groups together genes that have similar levels of expression.
