How CRISPR Gene Editing Works: A Bacterial Immune System Turned Scientific Breakthrough
Summary
This article discusses CRISPR, a groundbreaking gene-editing technology derived from a bacterial immune system that evolved over a billion years ago. It explains how bacteria defend against viruses by snipping viral DNA fragments, storing them in their genome, and using them to recognize and destroy returning threats. The CRISPR-Cas9 system uses guide RNA to identify and edit specific DNA sequences, representing a major scientific discovery with profound implications for genetics and medicine.

· 4 pulledOne of the most surprising and remarkable discoveries in recent scientific history has been CRISPR.
CRISPR is a form of immune system that evolved in bacteria more than a billion years ago to defend against persistent viral threats.
Under attack, bacteria can snip a small fragment of a virus's DNA, store it in the CRISPR region of their genome, and then use it to recognize and destroy the same virus if it returns.
The CRISPR-Cas9 system, to give it its longer name, consists of a short strand of guide RNA that identifies where
