When a bacterium encounters a virus, it can capture a snippet of the viral DNA and integrate it into its own CRISPR array. The technology allows scientists to edit DNA with unprecedented accuracy, accelerating work in agriculture, medicine, and basic biology.
The Patent Race Behind CRISPR Technology
This elegant adaptive immune system is the biological foundation for CRISPR technology. Phage Defense Mechanism Scientists theorized that these spacers were molecular memories from past viral infections.
Researcher Contribution Year Francisco Mojica Identified the repeating DNA patterns in microbes 2000s Emmanuelle Charpentier Demonstrated the use of tracrRNA with Cas9 2011 Jennifer Doudna Simplified the system into a two-component tool 2012 The Simplification and Engineering Leap The natural CRISPR system is complex, requiring multiple RNA molecules to function. The true simplification that made CRISPR a ubiquitous tool came from the work of Jennifer Doudna and Emmanuelle Charpentier in 2012.
The Patent Race Behind CRISPR Technology
Impact and Ethical Considerations. Ultimately, the foundational patent for the CRISPR-Cas9 gene editing process in eukaryotes was awarded to the Broad Institute, while Doudna and Charpentier received the Nobel Prize in Chemistry in 2020 for their contributions.
