WebJul 15, 2024 · The CRISPR segments identify and flag the matching DNA in the viruses. But it’s particular enzymes, including one called Cas9, that serve as weapons against the invaders. Cas9 carries a copy of the CRISPR sequence with it, searching for matching DNA in the viruses. Wherever it finds that matching DNA, Cas9 severs it and breaks it apart.
