Web6 apr. 2024 · Cas12 is a single RNA-guided endonuclease, which means it processes its own guide RNAs and so only requires crRNA for targeting, making it a smaller overall package than Cas9. The ability to design a targeting crRNA for both Cas9 or Cas12 is very straightforward and key to the simplicity and broad use of these systems in genome editing. Web30 apr. 2024 · CRISPR-Cas9 can be programmed to find and cut specific pieces of DNA, but editing the DNA to create desired mutations requires tricking the cell into using a new piece of DNA to repair the break.
