A gene chip is a highly specialized, stamp-sized piece of glass or plastic that is used to analyze thousands of genes at a time. They are also called [DNA chips]? or [DNA microarrays]?. |

Gene chips are covered with gridlike patterns of short DNA strands, called probes. Each probe can bind to a different gene sequence. When sample DNA is placed on the chip, researchers can study which probes bind to the sample to determine which genes were present in the sample. Genes from cancerous cells can be analyzed with gene chips to discover which genes are present in the cancerous cells that are not present in healthy cells. Ggenes can be treated with drugs, and the gene chip can analyze those genes to determine which genes are turned on or off by the drug. |
