The art and science of fixing faulty genes

UC Berkeley biochemist Jennifer Doudna and her colleagues say they can edit any organism’s DNA using an RNA-guided protein found in bacteria. This technology, called CRISPR-Cas9, could redefine the possibilities for editing human and non-human genes, opening the door to societal and ethical implications.
