Did Jennifer Doudna Invent CRISPR?
The journey towards the discovery and development of the revolutionary gene-editing technology known as CRISPR-Cas9 is a narrative that transcends geographical boundaries and scientific disciplines. It is a tale of collaborative scientific discovery, and a key player in this narrative is biochemist Jennifer Doudna. To fully understand Doudna’s role in the development of CRISPR-Cas9, we must first delve into the history of CRISPR and the many scientists whose work contributed to this revolutionary technology.
What is CRISPR?
CRISPR, or Clustered Regularly Interspaced Short Palindromic Repeats, is a segment of DNA found in bacteria and archaea. It forms part of an ancient bacterial defense system against viruses. Essentially, CRISPR sequences help bacteria remember viruses that have attacked them, and if the same viruses attack again, the bacteria can recognize them and launch a counterattack using CRISPR-associated proteins, or Cas proteins.
The most famous of these Cas proteins is Cas9, which works like a pair of molecular scissors to cut the DNA of invading viruses. Scientists saw potential in this system for editing the DNA of other organisms, including humans, which led to the development of the CRISPR-Cas9 gene-editing technology.
The Journey to Discovering CRISPR-Cas9
The discovery of the CRISPR-Cas9 system was a collaborative effort that took many years and involved many scientists across different fields and countries.
In the late 1980s and early 1990s, researchers like Yoshizumi Ishino and Francisco Mojica first noticed unusual, repetitive sequences (later known as CRISPR sequences) in bacterial DNA but didn’t understand their function.
Mojica and his team, including Ruth-Marie Marraffini, later discovered the defensive role of these sequences against viruses. Around the same time, another scientist, Alexander Bolotin, discovered one of the Cas proteins, which he named Cas9.
Jennifer Doudna and Emmanuelle Charpentier
This is where Jennifer Doudna and her collaborator, Emmanuelle Charpentier, enter the scene. While many scientists were instrumental in uncovering the existence and function of CRISPR sequences and Cas proteins in bacteria, it was Doudna and Charpentier who realized the potential of this system for gene editing in other organisms.
In 2012, Doudna and Charpentier published a landmark paper in the journal Science describing how the CRISPR-Cas9 system could be used as a tool to make precise, targeted changes to the DNA in cells of other organisms, including human cells. They showed how the system could be programmed to cut DNA at specific locations, allowing scientists to remove, add, or alter genetic material with unprecedented precision.
This breakthrough transformed the CRISPR-Cas9 system from a fascinating piece of bacterial biology into a powerful tool for genetic engineering. It opened up new possibilities in a variety of fields, from medicine to agriculture, making it possible to edit the genes of any organism with a level of ease and precision that had previously been unachievable.
Did Jennifer Doudna Invent CRISPR?
So, did Jennifer Doudna invent CRISPR? The answer requires a nuanced understanding of scientific discovery. Doudna did not ‘invent’ CRISPR in the sense of creating it — CRISPR is a naturally occurring biological system found in bacteria.

Jennifer Doudna: 2020 Nobel Prize in Chemistry
The story of Jennifer Doudna and her journey to winning the 2020 Nobel Prize in Chemistry is one marked by relentless curiosity, groundbreaking research, and an impactful scientific partnership. In collaboration with Emmanuelle Charpentier, Doudna developed the revolutionary CRISPR-Cas9 gene-editing tool, transforming the field of genetics and earning the highest accolade in their discipline.
Early Research and Work
Born in Washington, D.C., and raised in Hilo, Hawaii, Doudna’s interest in biochemistry and molecular biology led her to study these subjects at Pomona College in California and then at Harvard Medical School, where she earned her doctorate. As a postdoctoral fellow at the University of Colorado, Doudna worked under Thomas Cech, who had won the Nobel Prize in Chemistry in 1989 for his work on the catalytic properties of RNA.
At the University of Colorado, Doudna dove into the world of RNA, a molecule that, like DNA, is crucial for life as we know it. She continued her exploration of RNA as she moved on to faculty positions at Yale University and then the University of California, Berkeley.
Meeting Emmanuelle Charpentier
In 2011, Doudna attended a conference in Puerto Rico where she met French microbiologist Emmanuelle Charpentier. Charpentier had been studying a molecule known as tracrRNA in the bacteria Streptococcus pyogenes, and she believed that it played a crucial role in the bacteria’s immune response.
Intrigued by Charpentier’s work and seeing a connection to her own research into RNA, Doudna proposed a collaboration. They set out to investigate the bacteria’s immune system further, and their partnership would ultimately lead to a revolutionary breakthrough.
Together, Doudna and Charpentier made a stunning discovery: bacteria have a kind of ‘adaptive immunity’ thanks to a system known as CRISPR-Cas9. When a virus attacks a bacterium, the bacterium can incorporate a piece of the virus’s DNA into its own genome in a region called the CRISPR sequence. If the same virus attacks again, the bacterium uses RNA transcribed from the CRISPR sequence to guide the Cas9 protein to the virus’s DNA, which it then cuts, disabling the virus.
In 2012, Doudna and Charpentier published a paper in the journal Science in which they showed that they could ‘program’ the CRISPR-Cas9 system to cut not just viral DNA, but any DNA sequence at a specified location. This effectively turned CRISPR-Cas9 into a highly precise gene-editing tool that could be used in a wide range of organisms, not just bacteria.
Recognition and the Nobel Prize
The paper was met with widespread acclaim. The implications of Doudna and Charpentier’s work were profound: the ability to edit genes with such precision opened up possibilities in many fields, from medicine to agriculture to biofuels.
