Few individuals can be unmoved by the impact of molecular biology. Advances in the discipline over four decades have progressed at a rate unrivalled in other scientific areas. In its formative years, molecular biology examined the chemical and physical structures of biological molecules, subsequently elucidated the nature and function of DNA and evolved into molecular genetics. From this exponential growth of scientific knowledge, tremendous opportunities were created for the application of molecular approaches to solve problems in applied biology. This book describes the new productive...
