CRISPR Immunity Explained: How Cas9 Protects Bacteria from Viruses

CRISPR-Cas9 is well-known as a genome-editing tool that lets scientists rewrite DNA, but it originally evolved in bacteria. So what does CRISPR do in nature? And by what mechanism? This animation explains how the CRISPR-Cas immune system works to defend bacteria from viruses called bacteriophages.
