Z_5_10 — Genome Editing Beyond CRISPR: TALENs, Base Editors, Prime Editors, and Next-Generation Tools

While CRISPR-Cas9 (covered in Z_1_02) dominates the genome editing landscape, it is neither the first nor the only precision genome editing technology. The field began with zinc finger nucleases (ZFNs) in the early 2000s
