Old tricks, new dog: CRISPR/Cas9 is a powerful tool for gene editing that requires an endonuclease (Cas9) and RNA strands. It has been shown that chemical modification of the RNA structures, an approach that has been used to improve the efficiency of RNA interference, can also be applied to enhance the activity of CRISPR/Cas9 and reduce its off-target effects.
