Unravelling a genetic mystery Research by a University of Nottingham expert has shed new light on a genetic mystery that has its origins millions of years ago.A study by Dr Angus Davison has helped to uncover new facts about the most common organic compound found on earth - a substance called cellulose.Cellulose is found in large amounts in all crops and plant life, making it one of the foundations of modern farming, human diet and the global economy.There is just one problem with it: most animals are unable to directly digest it in their own stomachs, because they lack a key gene to enable them to do this.
