A DNA "shredder" is the latest CRISPR gene-editing tool

A new gene-editing enzyme called CRiSPR-Cas3 could function like a "DNA shredder"

The CRISPR gene-editing system is one of the most important medical breakthroughs of recent years, but that doesn't mean it's perfect. The most common enzyme in use is Cas9, which acts like a pair of molecular scissors and enables precise cut-and-paste DNA edits. But now, researchers have developed a new genetic tool that, they say, acts more like a motorized DNA "shredder."
