Programmable RNA Cleavage of DNA (image) DOE/Lawrence Berkeley National Laboratory Share Print E-Mail Caption Programmable DNA scissors: A double-RNA structure in the bacterial immune system has been discovered that directs Cas9 enzymes to cleave and destroy invading DNA at specific nucleotide sequences. This same dual RNA structure should be programmable for genome editing. Credit (Image by H. Adam Steinberg, artforscience.com) Usage Restrictions contact H.
