For more than four decades, Molecular Biology of the Cell has distilled the vast amount of scientific knowledge to illuminate basic principles, enduring concepts, and cutting-edge research. The Seventh Edition has been extensively revised and updated with the latest research, and has been thoroughly vetted by experts and instructors. The classic companion text, The Problems Book, has been reimagined as the Digital Problems Book in Smartwork, an interactive digital assessment course with a wide selection of questions and automatic-grading functionality. The digital format with embedded animations and dynamic question types makes the Digital Problems Book in Smartwork easier to assign than ever beforeÑfor both in-person and online classes.
