CRISPR is a technology that can be used to edit genes and, as such, will likely change the world. The essence of CRISPR is simple: it’s a way of finding a specific bit of DNA inside a cell.

Techniques such as site-specific recombinases, CRISPR systems ... Researchers modified Escherichia coli using a chimeric Cas1–Cas2 reverse transcriptase system to record their global ...
