Gene-editing is the process of altering a part of DNA — the code that governs much about how an organism develops and behaves. It can correct or delete parts of that code, or insert sections, for reasons that include preventing disease.

A key tool for editing is the CRISPR-Cas9 process, which uses CRISPRs — a part of the immune defence system in bacteria — to locate a target in the
