The Molecules of Life explains how the chemistry and physics of organic molecules drive processes within cells and permit the construction of amazingly complex plants and animals. Describing some of the basic concepts needed to understand the field and discussing the methods used to explore the structures and behavior of DNA, RNA, and proteins, this new book is devoted to stories about how these molecules carry out the business of life. The Molecules of Life shows how and why scientists study biological molecules, including how they are built, how they interact with each other, and what roles they play in the lives of cells and organisms.
