open Background Essay

While human DNA sequences look like alphabet soup to most people, the Human Genome Project has begun to decipher the code into individual genes. As more gene locations are mapped, new tests will become available for genetic diseases and disorders. This article by the National Cancer Institute and the National Center for Human Genome Research offers a genetics primer, explains how genetic testing works, and helps users decide how they feel about this new technology.
