CRISPR/Cas9 is a precise gene editing technique whose development by Jennifer A. Doudna and Emmanuelle Charpentier was recognized with the 2020 Nobel Prize in Chemistry. Commonly known as "genetic scissors," CRISPR allows the introduction of the desired DNA sequence into (virtually) any spot of the genome, thus modifying or inactivating a gene. This technique is widely used in biomedical research and some CRISPR-based therapies are in clinical trials for the treatment of human blood disorders, some types of cancer and HIV, among other conditions.
