WebAug 3, 2024 · Strands of RNA and DNA can bind to each other when they have matching sequences. The RNA portion of the CRISPR, called a guide RNA, directs Cas9 enzyme to the targeted DNA sequence. Cas9 cuts the genome at this location to make the edit. CRISPR can make deletions in the genome and/or be engineered to insert new DNA sequences. WebHow does it work? The CRISPR-Cas9 system consists of two key molecules that introduce a change ( mutation?) into the DNA. These are: an enzyme? called Cas9. This acts as a pair …
