CRISPR-Cas9: Programmable Gene Editing
Doudna and Charpentier discover that a bacterial immune system can be reprogrammed to edit any DNA sequence. Biology becomes software.
In June 2012, Jennifer Doudna (UC Berkeley) and Emmanuelle Charpentier (Umeå University) published their discovery that the CRISPR-Cas9 system—a natural defense mechanism in bacteria—could be reprogrammed to cut any specific DNA sequence. This turned gene editing from an expensive, imprecise art into a cheap, precise, programmable tool. They won the 2020 Nobel Prize in Chemistry.

Verified Facts
- CRISPR-Cas9 acts like molecular scissors: a guide RNA directs the Cas9 protein to a specific DNA sequence, where it makes a precise cut.
- Before CRISPR, editing a single gene cost ~$5,000 and took months. CRISPR reduced this to ~$75 and a few days.
- Doudna and Charpentier won the 2020 Nobel Prize in Chemistry—just 8 years from discovery to Nobel, one of the fastest in history.
- Feng Zhang (Broad Institute) independently demonstrated CRISPR editing in human cells in 2013, sparking a patent dispute that lasted years.
