Advances in the fields of molecular biology and genetic engineering are beginning to directly impact clinicians in disease prevention, diagnosis, and treatment. Therefore, an understanding of molecular biology is rapidly becoming necessary to fully understand normal physiology and pathophysiology. The book focuses on the latest advances and innovations in methods for molecular biology and biotechnology investigation such as DNA cloning, cut and paste DNA, bacterial transformation, transfection, chromosome integration, cellular screening, cellular culture, and extraction of DNA.
