DNA

A Life Altering Discovery
Fifty years ago, James Watson and Francis Crick made one of the world's most important scientific breakthroughs when they discovered the double helix structure of DNA. Unlocking the secret of life unleashed a race to catalogue human genes, the success of which has transformed our lives and presented unknown implications for our futures. In the new five-part series DNA, a definitive look at the history of DNA science and its vital role in various aspects of human life, Watson provides his unique and sometimes controversial perspectives on subsequent genetic discoveries, and former President Bill Clinton discusses his involvement in the Human Genome Project. The series also examines how DNA science contributes to our understanding of such health issues as Alzheimer's disease, Down syndrome and depression, three subjects addressed in WHYY's new series Circle of Love airing on TV12 this month. -- Mary Eileen O'Connor
