New CRISPR patent hearing continues high-stakes legal battle Tilis 2 years ago CRISPR-Cas9 gene editing complex, molecular structure. The CRISPR-Cas9 protein (orange) is used in genome engineering to cut DNA (deoxyribonucleic acid). It uses a guide RNA (ribonucleic acid) sequence (red) to cut DNA (blue) at a complementary cleavage site.
