Simple technology makes CRISPR gene editing cheaper

The CRISPR-Cas9 gene editing tool requires an RNA guide to precisely target a segment of DNA, where the Cas9 enzyme can either cut or latch on with a fluorescent probe. Creating guide RNAs is time consuming and expensive, however. Researchers have found a simple, cheap way to produce these guides, making it easy to produce thousands simultaneously, even turning an entire genome into a library of tens of thousands of guide RNAs.
