Genes: Seeing is Believing

     Thanks to new technology, scientists are now able to view genes with their bare eyes. Because of this, we can now find what genes are doing their job, and which genes are causing things such as cancer or disease. The main piece of technology we use to see these genes is called a microarray. A microarray is a sort of scanning method where genes or DNA is placed or printed on a glass slide and then "scanned" different colors to distinguish between the unusual genes.

     The different colors represent, for example, the cancerous or noncancerous cells. The cancerous cells would be colored red, while the noncancerous cells would be green.
