Watch Genes Turn On in Living Cells: Most genes serve one main purpose: as recipes for the body’s proteins. The first step in activating genes to produce proteins is called transcription. Although scientists think they know how transcription works, it has not been well studied in real-time in living cells. Now, researchers have developed fluorescent dyes and new techniques in microscopy that will enable them to watch transcription from individual genes. Faulty gene transcription can lead to cancer, so a detailed understanding of the process may lead to new ways to treat disease.
