convenience of single homology arm donor DNA and CRISPR/Cas9-nickase for targeted insertion of long DNA fragment

ABSTRACT

Objective: CRISPR/Cas9 technology provides a powerful tool for targeted modification of genomes. In this system, a donor DNA harboring two flanking homology arms is mostly used for targeted insertion of long exogenous DNA. Here, we introduced an alternative design for the donor DNA by incorporation of a single short homology arm into a circular plasmid
