How to make the gene-editing tool CRISPR work even better

Scientists have found conclusive evidence that Cas9, the most popular enzyme currently used in CRISPR gene editing, is less effective and precise than one of the lesser-used CRISPR proteins, Cas12a. Because Cas9 is more likely to edit the wrong part of a plant's or animal's genome, disrupting healthy functions, the scientists make the case that switching to Cas12a would lead to safer and more effective gene editing.
