A team discovers a new family of enzymes capable of inducing targeted cuts in single-stranded DNA A few years ago, the advent of technology known as CRISPR was a major breakthrough in the scientific world. Developed from a derivative of the immune system of bacteria, CRISPR enables double strands of nucleotides in deoxyribonucleic acid (DNA) to be cut. This makes it possible to specifically modify a targeted gene in plant, animal and human cells. Ultimately, CRISPR became a preferred method in the search for treatments for acquired or hereditary diseases.
