Researchers invent new gene-editing tool – Phys.org

Researchers from the University of Illinois Chicago have discovered a new gene-editing technique that allows for the programming of sequential cutsor editsover time.
CRISPR is a gene-editing tool that allows scientists to change the DNA sequences in cells and sometimes add a desired sequence or genes. CRISPR uses an enzyme called Cas9 that acts like scissors to make a cut precisely at a desired location in the DNA. Once a cut is made, the ways in which cells repair the DNA break can be influenced…
