Genetic engineering is one of the most controversial and passionately debated issues today. This book is an in-depth, yet accessible, exposition of the science behind genetic engineering technology, written by a scientist who has herself carried out research in genetics and taught the subject for many years. It examines the social and political implications of the intimate involvement of genetic engineering science with big corporate business, and it points to serious hazards that are inherent in the technology but are largely ignored by practitioners and regulators alike. The author calls for a halt to commercialisation and for an independent public enquiry into the hazards involved, taking into account the most comprehensive scientific findings as well as the socio-economic and ethical implications.
