Fourth in a five-part series. Tells the story of how researchers have developed radically new ways to treat cancer by tracing it back to its origins: its DNA. Focuses on two pioneering efforts: the race between Dr. Mary Claire King and Dr. Mark Skolnick, founder of Myriad Genetics to isolate the gene linked to breast cancer, and Dr. Brian Druker's work that eventually led to an anti-cancer drug which cures Chronic Myeloid Leukemia. Also looks at the work of David Botstein in discovering gene markers and Per Lonning, Botstein and partner Pat Brown who developed a micro-array technique to reveal differences between seemingly identical cancers.
