WebThe CRISPR system is the basis of adaptive immunity in bacteria and archaea. It utilizes Cas nucleases, which are enzymes that can bind and create double-stranded breaks (DSBs) in DNA. When a bacterium is infected by a virus, it uses a Cas nuclease to snip off a piece of viral DNA known as a protospacer. WebA: CRISPR “spacer” sequences are transcribed into short RNA sequences (“CRISPR RNAs” or “crRNAs”) capable of guiding the system to matching sequences of DNA. When the target DNA is found, Cas9 – one of the enzymes produced by the CRISPR system – binds to the DNA and cuts it, shutting the targeted gene off.
