Genome editing refers to the intentional modification of a targeted DNA sequence in a cell which, by greatly improving our understanding of biological functions, is beginning to revolutionise research.

This powerful new tool has significant potential for application in a wide range of sectors in pursuit of various societal priorities in human and animal health, food and agriculture, the modification of populations in the wild (in particular insect disease vectors) and microbial biotechnology and the bioeconomy. However, alongside the prospective benefits of the technology, safety, ethical and other issues have been raised that need to be explored, and regulatory questions posed that need to be addressed.
