GENOME EDITING

Base editing goes into hyperdrive

CRISPR base editors can induce single-base-pair changes in the genome, although they are often inefficient. A study now shows that fusion of the DNA-binding domain of RAD51 to base editors enhances both the efficiency and the targeting range of optimized enzymes. These ‘hyper-editors’ offer effective tools for disease modeling and gene therapy.
