(Epi)Genome editing systems. a Zinc Finger Nuclease (ZFN), b Transcription-Activator-Like Effector Nuclease (TALEN), c CRISPR/Cas9, d Zinc Finger (ZF) with a DNA methyltransferase effector domain, e Transcription-Activator-Like Effector (TALE) with a histone methyltransferase, and f Catalytically deactivated Cas9 (dCas9) and sgRNA from with a histone acetyltransferase. Components are not to scale as critical features are exaggerated and some non-variable features are removed
