A Genetic ‘Chain Saw’ to Target Harmful DNA
October 26, 2016
(The Wall Street Journal) – Many people are excited by the potential of the genetic tool Crispr-Cas9 to serve as a kind of molecular scissors to cut and repair malfunctioning DNA. The tool has generated hundreds of millions of dollars in investment, a tense patent battle and even a forthcoming Jennifer Lopez TV drama. But Cas9 isn’t the only possible application of Crispr. Dr. Barrangou, now a food scientist who runs a Crispr lab at North Carolina State, is among a growing number of researchers who think that other approaches may reach doctors and patients more quickly.
