Now fully updated and revised, the new Fourth Edition of Cell and Molecular Biology: Concepts and Experiments not only offers you and your students all of the latest research, it also gives students the tools they need to understand the science behind cell biology and ultimately succeed in your course. Karp explores core concepts in considerable depth, and presents experimental detail when it helps to explain and reinforce the concept being explained. This edition also continues to offer an exceedingly clear presentation and excellent art program, both of which have received high praise in prior editions.
