CRISPR based gene insertion, replacement, or correction
Mechanism of CRISPR HDR based gene editing
CRISPR/Cas9 technology is commonly used to create precise double stranded breaks (DSBs) at target DNA sites. The guide RNA (gRNA) recognizes the protospacer adjacent motif (PAM) sequence on the target DNA after forming complex with Cas9, then Cas9 exerts its endonuclease function to cause DSBs. This triggers two mechanisms for repair: one is non-homologous end-joining (NHEJ), which introduces mutations in the DSB site. The other mechanism is homology directed repair (HDR) which enables the donor DNA to be inserted at the break site and create gene knock-ins.
