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. Natural Origins: The Discovery in Bacterial Immunity The inventor of CRISPR is not a single individual working in a vacuum, but rather the cumulative effort of microbiologists studying how bacteria defend themselves.
Who Invented CRISPR Gene Editing and How It Revolutionized Science
This elegant adaptive immune system is the biological foundation for CRISPR technology. The work transformed these mysterious genomic spots into a functional system, revealing the proteins, such as Cas9, that act as the molecular scissors.
They engineered a single-guide RNA (sgRNA) that combines the targeting function of crRNA and the processing role of tracrRNA. When a bacterium encounters a virus, it can capture a snippet of the viral DNA and integrate it into its own CRISPR array.
Who Invented CRISPR Gene Editing and How It Revolutionized Science
The technology allows scientists to edit DNA with unprecedented accuracy, accelerating work in agriculture, medicine, and basic biology. If the same virus attacks again, the bacterium produces RNA copies of the spacer sequences that guide defensive proteins to the viral DNA, effectively neutralizing the threat.
