You are working in a cancer lab and are interested in identifying some genes that are important in the onset of lung cancer. You have several genes you think may be involved, so you "print" spots of the candidate DNA sequences on a microarray slide. After doing this, you isolate mRNA from both normal lung cells and cancerous lung cells. You make fluorescently-tagged cDNA from each mRNA sample; the cDNAs from normal cells are tagged with a green-colored molecule and the cDNAs from cancer cells are tagged with a red-colored molecule. You hybridize the cDNAs with the microarray and get the following data. (Green spots are labeled with "G", red spots are labeled with "R".)
