Scientists create revolutionary gene editor

Thanks to CRISPRoff technology, individual genes can be turned off in a reversible way, without permanently interfering with the DNA structure. The CRISPR-Cas9 editor used so far has brought revolutionary progress in the field of gene editing, but its use was associated with a permanent interference in DNA and the risk of unwanted mutations. "We can now silence any part of the genome, making it a great tool to study its function," argues Jonathan Weissman, professor of biology at MIT.
