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. WebCas9 (CRISPR associated protein 9, formerly called Cas5, Csn1, or Csx12) is a 160 kilodalton protein which plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids, and is heavily utilized in genetic engineering applications. Its main function is to cut DNA and thereby alter a cell's genome. The …
