CRISPR systems are RNA-guided microbial adaptive immune systems that have been repurposed for applications in medicine, pharmacology, and agriculture. The hallmark of CRISPR immune systems is the CRISPR sequence contained in the host chromosome, which consists of short direct-repeats of 20-40 bases, followed by unique spacer sequences of about the same length. In 2005 several bioinformatics groups discovered that CRISPR spacer sequences in bacteria and archaea were identical to known microbial pathogens such as viruses and plasmids, suggesting that CRISPRs serve as a molecular memory of encounters with foreign nucleic acid. Since 2005 basic research on these systems has revealed …
