The CRISPR-Cas9 system cuts DNA at specific sequences, guided by RNA for precise targeting.

“It's the way that it cuts that has made it really catch on in a way that none of these earlier technologies do. So crisper, if you think of it as a it's an enzyme that can cut DNA and it it can cut essentially almost any sequence of DNA. So how does it decide which sequence to cut? It does it by actually pairing with an RNA molecule. So crisper sometimes called cast 9 which is a particular type of crisper system um is a is a combination of a protein which is a scissor and then an RNA that sticks to it and the RNA is what actually programs where that scissor will cut.”
