Genetic scissors: a tool for rewriting the code of life.
Emmanuelle Charpentier and Jennifer Doudna are awarded the Nobel Prize in Chemistry 2020 for discovering one of gene technology’s sharpest tools: the CRISPR/Cas9 genetic scissors. Researchers can use these to change the DNA of animals, plants and microorganisms with extremely high precision. This technology has revolutionised the molecular life sciences..
The gene editor called CRISPR-Cas9 is one such unexpected discovery with breathtaking potential. When Emmanuelle Charpentier and Jennifer Doudna started investigating the immune system of a Streptococcus bacterium, one idea was that they could perhaps develop a new form of antibiotic. Instead, they discovered a molecular tool that can be used to make precise incisions in genetic material, making it possible to easily change the code of life.
