Article Correctness Is Author's Responsibility: Discovery helps improve accuracy of CRISPR-Cas9 gene editing

A detailed study of how domains within the Cas9 protein move when the molecule binds to DNA has allowed scientists to locate the protein that monitors the fidelity of binding between the Cas9 single-guide RNA and its DNA target. The researchers then tweaked this domain to boost specificity, creating the highest fidelity Cas9 protein to date.
