Completely revised and updated with the latest findings in the field， the second edition of Lewins Essential GENES provides students with a fundamental background in molecular biology and molecular genetics. An exceptional new pedagogy enhances student learning and helps readers understand and retain key material like never before. New Concept and Reasoning Checks at the end of each chapter section， End of Chapter Questions and Further Readings sections， and several categories of special topics boxes expand and reinforce important concepts. The reorganization of topics allows students to focus more sharply on the key material at hand and improves the natural flow of course material. New end-of-chapter questions review major points and allow students to test themselves on important course material.
