Barrangou and a team of researchers at Danisco first experimentally demonstrated the technique of CRISPR (Clusters of Regularly Interspaced Short Palindromic Repeats). To fight off the infecting bacteriophages, the bacterial immume systems (CRISPR-Cas9) specifically target genomic sequences. Cas9 is an enzyme that cuts DNA which is associated with the specialized stretches of CRISPR DNA.
This figure clearly depicts how the bacterium protects itself from the infecting viruses (bacteriophages).
