Caption: Ty Lebsack (right) and Jose Munoz-Rodriguez used “gene chips” to analyze the expression levels of more than 20,000 genes. A laser scans the chip for fluorescent markers serving as an indirect indication of the level of gene activity. Software then analyzes the resulting pattern of microscopically small dots on the chip and displays it on a computer monitor.
