"CRISPR is a bacterial immune system. You know how human beings have an immune system and it protects us from getting a flu or getting a cold?” said Jenny Hsieh, a biology professor at UT San Antonio, who runs the Hsieh Lab.

“Bacteria are also trying to fight off things that will kill (them), and that's what CRISPR is."

Scientists modified the CRISPR bacterial immune system so it could work in human cells. It includes an enzyme called Cas9 that can cut out pieces of human DNA.
