A proven teaching aid for the Third EditionThe Problems Book is designed to help students appreciate the ways in which experiments and simple calculations lead to an understanding of how cells work. Each chapter is subdivided in the same way as Molecular Biology of the Cell and provides a rehearsal of key terms, tests for understanding basic concepts, and research-based problems. Chapters 6 through 19, from "Basic Genetic Mechanisms" to "Cell Junctions, Cell Adhesion, and the Extracellular Matrix" are covered in this way. -- Completely reorganized to match the Third Edition of Molecular Biology of the Cell. -- Contains 50 new problems, including an entirely new chapter on genetic engineering methods. -- Gives detailed answers for half of the problems to help students learn how to analyze experimental observations and draw conclusions from them. -- Comes with a special booklet, given to teachers on request, that provides answers to the other problems. -- Provides unanswered problems that are useful for homework assignments and as exam questions.

As the amount of information in biology expands dramatically, it becomes increasingly important for textbooks to distill the vast amount of scientific knowledge into concise principles and enduring concepts. As with previous editions, Molecular Biology of the Cell, Sixth Edition accomplishes this goal with clear writing and beautiful illustrations. The Sixth Edition has been extensively revised and updated with the latest research in the field of cell biology, and it provides an exceptional framework for teaching and learning.§The entire illustration program has been greatly enhanced. Protein structures better illustrate structure-function relationships, icons are simpler and more consistent within and between chapters, and micrographs have been refreshed and updated with newer, clearer, or better images. As a new feature, each chapter now contains intriguing open-ended questions highlighting "What We Don't Know," introducing students to challenging areas of future research.§Updated end-of-chapter problems reflect new research discussed in the text. Thought-provoking end-of-chapter questions have been expanded to all chapters, including questions on developmental biology, tissues and stem cells, the immune system, and pathogens.§
