Why can identical twins develop different diseases like schizophrenia? Why are tortoiseshell cats always female? Why was Audrey Hepburn so delicately beautiful? Why do we age, develop disease or become addicted to drugs? Astonishingly, the answers to all these questions lie in epigenetics. The fasting moving field in biology today, it has at its heart the realisation that cells read genetic code more like a script to be interpreted than a blueprint that replicates the same result each time. Biologist Nessa Carey deftly takes us through the thrilling developments epigenetics has undergone in recent years, explores the far-reaching consequences it has for our understanding of life, and reveals the amazing possibilities that epigenetics holds for each of us in the surprisingly near future. A fascinating and thought-provoking book that will teach you all you need to know about DNA and genetics. This paperback book has 340 pages and measures: 19.7 x 12.7 x 2cm.
