Targeted endonucleases technologies such as CRISPR/Cas9, TALEN, and ZFN induce targeted double-strand breaks that can be repaired via (1) error prone, non-homologous end joining to produce insertions and deletions, or (2) homology-directed repair with a donor template to produce specific point mutations or a variety of knock-ins (conditional ready, reporter etc.)
