Jennifer Doudna challenges governments, universities and investors to seize the moment and radically expand gene editing revolution
In a life-changing collaboration with the French scientist Emmanuelle Charpentier, we figured out how the chemistry of this process could be harnessed not to destroy viral DNA, but to cut the genome with unprecedented ease and accuracy in virtually any cell. This niche discovery has spurred an entire biotech revolution of its own. In animal and plant cells, cutting DNA with CRISPR-Cas9 allows us to turn some genes off and to turn others on.
An FDA-approved edit to cattle genes re-creates a slick coat, occasionally found in nature, that allows cows to tolerate increasing temperatures; using CRISPR to breed a tomato variety, approved for sale in Japan, has enhanced its nutritional qualities. For other crops, CRISPR is being used to increase yield, reduce pesticide and water use, and protect against disease.
