For every intron-containing gene in the yeast genome, the microarray included three synthetic DNA probes: splice-junction probes to detect spliced messenger RNA; intron probes to detect uns...Gene profiles predict survival
.... Microarrays, also known as gene chips, are glass slides that have been coated with thousands of spots of DNA, each representing a different gene. When a gene is active in a cell, it produces RNA copies known as transcripts. To measure the activity of genes, researchers use the RNA transcripts to make a fl...Researchers identify genes associated with aging of the retina
