Genome Editing: A Slippery Slope?

On September 18th, a research team from the Massachusetts Institute of Technology released a report detailing advancements in the genome-editing CRISPR system. The CRISPR system releases an enzyme that cuts and removes certain sections of DNA that are damaged or mutated and replaces them with a healthy DNA sequence. However, these scientists discovered a new enzyme, Cof1, which may now serve as an alternate to the previously used enzyme Cas9. Using this new enzyme, research teams have the ability to narrow their focus to very specific sections of the DNA double helix. Additionally, the CRISPR system cuts DNA in a different way, improving the efficiency and quality of the repair site.
