The CRISPR-Cas9 gene-editing technique is an important concept to know about in these days of biotech advances, but it can be pretty difficult to visualize properly. Is it really like molecular scissors? Where does the DNA go? Is it a big molecule or a small one? Fortunately a group has created a 3D animation of the process that shows it at the molecular level. You can watch the animation, created by biologists at Russia's Skoltech Institute and the Visual Science organization, below or at the latter's website: Wonder how accurate it really is? It got the thumbs-up from none other...
