WebCRISPR is one immune system that many bacteria use to fight viruses. CRISPR is special because it remembers previous phage attackers. How does it do this? The bacteria takes small pieces of DNA from invading phages. Then, it stashes them in its own genome, like a mugshot of what to look for. These DNA mugshots are called “CRISPR.” WebOct 6, 2024 · CRISPR is a gene-engineering technology that uses sequences of DNA and their associated proteins to edit the base pairs of a gene.
