This book is written specifically for students enrolled in BS161, Cell and Molecular Biology, at Michigan State University. Each chapter corresponds to one class day, and chapters are arranged to correspond with a typical BS161 schedule. Some chapters reference in-class activities, upcoming exams, and other course-specific elements—these are separate from the textbook and are only available to students in BS161.

For students in BS161, please note that this textbook is one of many resources provided to you. We recommend that you use this book in conjunction with pre-class recorded lectures, notes from in-class activities, and weekly quiz feedback to construct your understanding. We also strongly encourage you to form a study group with other classmates, as talking about biology with others is a great way to test your understanding and connect with material!
