Understanding DNA: The Molecule & How It Works

Understanding DNA explains step-by-step, why DNA forms in specific structures, the nature of these structures, and how they fundamentally affect the biological processes of transcription and replication. Containing more than 100 illustrations, several in full color, Understanding DNA describes the basic units of DNA and how these form the double helix, characterizes the various existing types of DNA double helix that exist, and explains how and why DNA twists and curves. It also discusses the mechanisms of DNA supercoiling, summarizes the assembly of DNA and protein into chromosomes, and outlines simple exercises, further reading, and a bibliography at the end of each chapter.
