CRISPR-Cas9 becomes a programmable DNA-cutting tool

Jinek, Charpentier, Doudna and colleagues showed how RNA could guide Cas9 to cut selected DNA, providing a crucial method for subsequent genome editing.

An original diagram evokes this era’s themes. It is not a historical artifact, a documented scene or a picture of this particular event.

The story

The paper investigated bacterial immunity and demonstrated designed guide RNAs directing Cas9 cleavage of DNA in vitro. Its authors were Jinek, Chylinski, Fonfara, Hauer, Doudna and Charpentier. This was a key programmable-cleavage experiment, not completion of every cellular or clinical application. Earlier CRISPR discoveries and later genome-editing work also involved additional researchers and independent teams.

Connections and context

Research on microbial defenses produced an unexpected experimental tool. DNA cutting, safe treatment, heritable effects and ethical judgments remain distinct questions requiring different evidence.
