Chinese scientists allegedly develop a new ‘controllable, reversible’ gene-editing technique

Scientists from the Chinese Academy of Sciences have developed a new gene-editing approach using CRISPR technology. The Cas13d-N2V8 system uses the Cas13 enzyme, which targets RNA. RNAs are transient molecules that only exist in the cell for a short period of time and are not integrated into the genome. The scientists claim that the Cas13 gene editing system is reversible and safer and more controllable compared to CRISPR-Cas9.
