The enormous advances made in molecular biology have allowed scientists to manipulate DNA with relative ease. This means that molecular biology has become a widely-used tool for answering scientific questions that may be quite unrelated to genetics and cell biology. The techniques have become a means to an end, rather than an end in themselves. They represent an invaluable method for obtaining research material to answer a variety of questions from a wide range of research areas about biological systems and their fundamental processes. This new book focuses on the most important techniques needed by undergraduate and post-graduate students when undertaking research in this area. Written in an accessible style and adopting a 'discovery' approach, to encourage the students to explore and experiment for them selves, this book will be invaluable to novices required and interested in learning these techniques.
