Genetic engineering is a rapidly growing field in the area of biological sciences. The driving forces behind this are the challenges encountered by health sectors, agriculture, the environment, and industry. As such, accurate and comprehensive knowledge about the philosophy, principles and application of genetic engineering is indispensable for students and researchers to harness maximum opportunities from this field of science. This volume gathers together comprehensive information regarding genetic engineering from recent studies, and presents it in a coherent manner. As such, it will be of interest to undergraduate and postgraduate students and researchers working in the biological sciences.
