DNA-Protein Interactions is a novel compilation of methods for studying the interactions of proteins with DNA. It is a rapidly advancing research area in which multidisciplinary approaches are especially valuable for solving problems and obtaining a detailed understanding of the molecular regulatory interactions involved. This book covers all the major tools that are required for the study of the large macromolecular enzymatic machines that manipulate DNA, with particular emphasis on biophysical techniques applied to the analysis of transcription and its relation to chromatin structure. Knowledge of basic techniques is assumed, although advances in fundamental fields are covered.
