Molecular machines : a materials science approach /
Molecular Machines presents a dynamic new approach to the physics of enzymes and DNA from the perspective of materials science. Unified around the concept of molecular deformability--how proteins and DNA stretch, fold, and change shape--this book describes the complex molecules of life from the inno...
