Molecular Biology of Assemblies and Machines presents a comprehensive narrative describing the structures of macromolecular complexes and how they assemble and interact. Written for advanced undergraduates, graduate students, and researchers in biochemistry, structural biology, molecular biology, biophysics, cell biology, and microbiology, this book will also appeal to those in chemistry, immunology, and medicine. Richly illustrated, the text explores the molecular mechanisms employed at the critical level between individual macromolecules and cells and organelles. Essentially all major biological activities are performed by assemblies of macromolecules (proteins, RNA, and DNA) acting in concert, many of which are endowed with machine-like properties. This unique book delves into these fascinating interactions, offering a detailed understanding of the intricate world of molecular biology.
