New DNA construct can set off a “mutagenic chain reaction”

By John Timmer for Atc Technika

A technique for editing genes while they reside in intact chromosomes has been a real breakthrough.Literally. In 2013, Science magazine named it the runner-up for breakthrough-of-the-year, and its developers won the 2015 Breakthrough Prize.

The system being honored is called CRISPR/Cas9, and it evolved as a way for bacteria to destroy viruses using RNA that matched the virus' DNA sequence. But it's turned out to be remarkably flexible, and the technique can be retargeted to any gene simply by modifying the RNA. Researchers are still figuring out new uses for the system, which means there are papers coming out nearly every week, many of them difficult to distinguish.
