WebSep 20, 2024 · How does CRISPR work? The main part of the CRISPR system is the Cas endonuclease, the Cas protein that cuts DNA strands. These Cas proteins can be programmed to find a 17- to 24-letter sequence by attaching a guide RNA that uniquely matches the specific DNA target. It’s similar to a key matching a lock.
