CRISPR breakthrough uses “hairpin lock” for more precise genetic engineering

The CRISPR gene-editing system is incredibly accurate, but when there are billions of base pairs of DNA to scroll through, it’s not unusual for it to be a little bit off target sometimes. Now, biomedical engineers at Duke University have created an RNA “lock” that can apparently make the system far more precise, and it works with all kinds of CRISPR variations.
