Evidence Snippets

First and second generation tools, such as zinc finger nucleases and transcription activator-like effector nucleases (TALENs), are limited by complex design and off-target effects.

Evidence 1Source 1DOI PubMedprovenance

The field has evolved from protein-based systems (e.g., zinc finger nucleases and transcription activator-like effector nucleases) to RNA-guided systems (e.g., CRISPR-Cas) that can control both genetic and epigenetic states.
