"WebCRISPR is one immune system that many bacteria use to fight viruses. CRISPR is special because it remembers previous phage attackers. How does it do this? The bacteria takes small pieces of DNA from invading phages. Then, it stashes them in its own genome, like a mugshot of what to look for. These DNA mugshots are called “CRISPR.” " - How is crispr used with bacteria and viruses

WebIt was subsequently discovered that bacteria transcribe these DNA elements to RNA upon viral infection. The RNA guides a nuclease (a protein that cleaves DNA) to the viral DNA to cut it, providing protection against the virus. The nucleases are named “Cas,” for “CRISPR-associated.” Genome editing 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 …
