Medical SEM and Micrograph Stock Photos: Microarrays, also called gene chips, are tools that let scientists track the activity of hundreds or thousands of genes simultaneously. For example, researchers can compare the activities of genes in healthy and diseased cells, allowing the scientists to pinpoint which genes and cell processes might be involved in the development of a disease.
