With a balance of topic coverage and depth this updated third edition covers the subject of biochemistry, and reflects the advances made in this field since the second edition published in 1981. These advances are incorporated without loss of historical perspective and without obscuring the main goal of the text: to teach the enduring fundamentals of the discipline. Included in the third edition is a completely reorganized part one introducing the flow of information from gene to protein. It emphasizes the growing interrelatedness of molecular biology and biochemistry, and acquaints one with experimental methods of both disciplines. Also included is 150 new problems and a wealth of new material on molecular genetics and cellular processes.
