Does this answer your question, or are you asking something else? > The problem addressed by the new technique is not the usual one discussed with CRISPR, namely, off-target effects. That refers to changing a region of the genome other than the intended one. While early genome-editing experiments had that problem, there has been “tremendous progress” in fixing it, said Dr. Keith Joung of Massachusetts General Hospital.
