Scientists Identify Gene Editing Enzyme

Scientist Jennifer Doudna, of the University of California Berkeley, and other researchers have identified an enzyme that allows them to "essentially change a genome at will to almost anything you want." CRISPR (clustered regularly interspaced short palindromic repeats) is a powerful tool that can help scientists, and perhaps one day doctors, alter an individual's genes, to prevent certain genetic diseases, whether in children or adults.
