You're correct, the full name is CRISPR/Cas9. CRISPR part is a short
sequence of RNA that is complementary to the place on the DNA that you want
to edit. The Cas9 is a protein enzyme that cuts DNA with a slight overlap
rendering the ends sticky so its easy to insert a gene there. The RNA
 positions the Cas9 with great precision so the cut is make just where you
want it to. It's much easier to use and makes fewer errors than previous
gene editing techniques.
