Illustration showing CRISPR Cas13 protein (grey) complexed to a guide RNA (pink-purple, centre). Once it has bound to the guide RNA, Cas-13 undergoes conformational change in shape that allows it to target and cleave target RNA and surrounding ssRNA. CRISPR-Cas complexes are used in genome engineering to cut DNA and RNA. | |
