Structural biology: Breaking the diffraction barrier


Short single-stranded DNA donors that asymmetrically span the Cas9 cut site show high efficiency in homology-directed editing. Among the many attractive features of the CRISPR–Cas9 system is its ability to replace a target sequence with a donor of choice. The efficiency of this homologydirected repair (HDR) varies widely depending on the cell type and… (More)
