    • When the virus attacks again, the bacterium quickly makes an RNA copy from the DNA archive and arms a secret weapon - a protein called Cas9.

      When the virus attacks again, the bacterium quickly makes an RNA copy from the DNA archive and arms a secret weapon - a protein called Cas9.

    • When it finds a 100% perfect match, it is activated and cuts out the virus DNA, making it useless, protecting the bacterium against the attack.
