It's a first step toward treating diseases like muscular dystrophy and neurodegeneration.

Despite the promise of gene editing for treating disease, altering genes can be risky and pose ethical challenges. So researchers from the University of California, San Diego and UC Berkeley instead focused on using the editing technique called CRISPR-Cas9 to manipulate the product of those genes. Back to freshman biology: As you may remember, double-stranded DNA makes single-stranded RNA, which makes proteins. Edit DNA and the proteins are altered forever. But edit the RNA and the genetic ma...
