DNA . Intro
DNA is the fundamental component of our genes and one of the molecules of life. The variation in DNA is what makes a fruit fly a fruit fly and a kangaroo a kangaroo. DNA is what makes each individual-whatever its species--unique. In this Web site, you will learn how DNA was discovered and how it functions. You will see how the ability to study whole genomes has revolutionized the study of DNA. You also will learn how this information gives scientists the means to manipulate DNA, enabling the discovery and production of new drugs and better food -- and creating new and unexpected controversies over how this technology will shape our lives and our future.
