In nature, bacteria use CRISPR-Cas9 to defend against viral infection (bacteriophages). When a bacterium survives a viral attack, it integrates a short fragment of the viral DNA into its own genome at the CRISPR locus. This locus then transcribes CRISPR RNA (crRNA) that guides the Cas9 nuclease to recognize and cleave any matching viral DNA upon reinfection.
