So the Cas9 -- I love to anthropomorphize -- so the Cas9 is kind of this Pac-Man thing that wants to chew DNA, and the guide RNA is the leash that's keeping it out of the genome until it finds the exact spot where it matches.
Dakle Cas9 -- volim antropomorfozirati -- tako da je Cas9 neka vrsta stvari poput Pac-Mana koja želi žvakati DNK, i vodička RNK je uzica koja ga drži izvan genoma dok ne nađe točno mjestso gdje se uklapa.
