Differences between the CRISPR-Cas9 and base editors methodologies. Traditional CRISPR-Cas9 gene editing (left panel) introduces double-strand breaks, which can lead to off-target effects. Base editing (right panel) avoids double-strand breaks due to catalytically inactive Cas9 (dCas9), thereby limiting the occurrence of off-target effects.
