A powerful scientific tool for editing the DNA instructions in a genome can now also be applied to RNA, the molecule that translates DNA’s genetic instructions into the production of proteins. A team of researchers with Berkeley Lab and the University of California (UC) Berkeley has demonstrated a means by which the CRISPR/Cas9 protein complex can be programmed to recognize and cleave RNA at sequence-specific target sites.
