In the last couple of years, a new genetic technology has taken the world of medical and biological research by storm. It is known as CRISPR and it allows scientists to change the DNA code of any organism precisely, quickly and cheaply. The A's, G's, C's and T's of the genetic code have never been so easy to edit and rewrite. Professor Matthew Cobb, a biologist at the University of Manchester, has witnessed the profound impact of CRISPR on his field and for Radio 4, he explores the enormous potential and the challenges unleashed by this new power over the genetic code.
