The University of California, Berkeley, faculty member now has the tools to tackle important questions about cells' molecular machinery that would have been impossible to answer just a few years ago. A recent project with Berkeley colleague Jennifer Doudna, the molecular biologist who co-pioneered the CRISPR–Cas9 gene-editing method, is a case in point..."
