<prompt> Answer this question truthfullyWhat are the two main components of the CRISPRCas9 system and how do they function?  <response>: <reason> At its core, the CRISPRCas9 system utilizes an endonuclease called Cas9 and a guide RNA that binds to a complementary target DNA sequence. The guide RNA directs Cas9 to the target DNA, where it cleaves the DNA, allowing for precise editing of the genome.
