Features
- A superior, pedagogically effective art program helps students learn the process of science, not just the facts, and has been enhanced in the Seventh Edition with two new types of Mini-captions.
- Multi-level Problem Sets at the end of each chapter help develop students' ability to analyze data, make generalizations and predictions, and apply their understanding to new situations.
- Techniques are introduced in the context of their use, which assists students' understanding while underscoring the importance of each technique. A Guide to Techniques and Methods helps readers locate the descriptions of experimental techniques and findings that are included in each chapter.
- Boxed Essays-Further Insights, Experimental Techniques, and Human Applications -give students insight into intriguing and exciting aspects of cell biology.
- All of the figures and micrographs are provided in PowerPoint? format on the Instructor Resource CD-ROM, along with animations from the companion website.


New to this Edition
- Two new types of Mini-captions are incorporated into selected figures to help students grasp concepts more quickly.
Text Box Mini-captions describe events taking place in various locations within a diagram.
Step Circle Mini-captions point to various steps within a sequential pathway and describe the events occurring at each step.
- A Bulleted Summary of Key Points has been added to the end of each chapter and briefly describe the main points from each section of the chapter
- Making Connections highlight connections among chapters and help students organize the material and keep sight of major course themes. Making Connections appear in every chapter, and they replace the Perspective sections from the previous edition.
- Content Updates have been added throughout the book and include extensive new coverage of MicroRNA and MicroRNAi (Chapter 23) to keep the text current while still maintaining the book's manageable length.

Continuing the tradition of its widely-praised previous editions, The World of the Cell, Seventh Edition, covers at the right depth and clarity- bioinformatics, bioenergetics, metabolism, enzyme kinetics, thermodynamics, membrane transport, cell signaling, regulatory mechanisms, transcription and translation, signal transduction, and DNA replication and recombination.

The new edition features information on Micro RNAis, other modern molecular techniques, and recent research advances without overwhelming students in detail. The World of the Cell's trademark features-art that teaches, Multi-level Problem Sets, and Concept Statements-have been augmented with new, time-saving study tools and “Mini-captions” for selected figures.
