Double-tap gene drive uses iterative genome targeting to help overcome resistance alleles
Abstract
CRISPR gene drives are genetic elements capable of quickly spreading through populations and they offer promising solutions for curbing the spread of vector-borne diseases and controlling crop pest and invasive species populations. Here the authors present a method for overcoming resistance alleles “double-tap,” that encodes additional gRNAs in the gene drive that target the most common generated resistance alleles.
