"... CRISPR is, in fact, a bacterial immune system. It’s an ancient system that evolved in microbes to allow prevention of viral infection. Our interest in this started with that fundamental biology, asking, “How does this work?” We did a collaborative research project with Emmanuelle Charpentier, a medical microbiologist, and our work with her laboratory revealed that one of the components of this CRISPR immune system is, in fact, a protein that’s called , that can be programmed to find and cut virus DNA. We published this work back in the summer of 2012, and for me, life hasn't been the same since."
