The announcement came in June. Berkeley Extension, the continuing education arm of UC Berkeley, was offering its first-ever introductory course—CRISPR Genome Editing: From Biology to Technology—on the revolutionary new tool that allows scientists to make precise edits in the genome. A lab and lecture course on CRISPR for anyone who has the interest (and money) to enroll? What a crazy idea. It seemed a bit like offering a workshop on how to enrich plutonium.
IN THE SUMMER OF 1984 the senior scientists of Cetus Corp., a Berkeley biotech company, found themselves in a bind. One of their employees, a promising young scientist named Kary Mullis, had dreamed up a technique to exponentially replicate tiny scraps of DNA. He called it polymerase chain reaction (PCR), and if it worked it would change the world and likely earn Cetus a mountain of money. The only problem was Mullis was an interpersonal wrecking ball.
