DNA-snipping protein called Cas9

Howard Hughes Medical Institute (HHMI) scientists have created a portrait of a DNA-snipping protein called Cas9 that reveals how the enzyme reshapes itself when it associates with an RNA molecule, creating a channel that lets it find and cleave its DNA target. The protein-RNA complex is a key component of a primitive bacterial immune system called CRISPR, and is also being used by researchers to cut specific DNA sequences in the laboratory for genome editing applications.
