Abstract
Editing the genome using approaches like TALEN and siRNA are already well tested. The new kid on the block is CRISPR-Cas9. CRISPR-Cas9 is rapidly evolving with impressive refinements for specificity, eliminating off-target effects, and versatility. One can adjust constructs and conditions to produce opposite effects on the genome and for a specific purpose. The nuances of the system, the means to significantly reduce off-targeting, and numerous applications are now emerging rapidly. This B&B commentary looks forward into how the CRISPR-Cas9 tool might serve the CCN field.
