Special enzymes can find these repeated phrases and snip the DNA strands there; the cell then naturally stitches up the damaged DNA, so the organism can keep using it. But the method still isn’t perfect—mistakes still happen more often than researchers would like. Now a team of biologists, led by researchers from the Broad Institute of MIT and Harvard, have found a tiny molecule that, when used with CRISPR, may make the editing process more precise, according to a study published last week in Cell. Most researchers editing DNA using...
