This was not something that could safely have been A anticipated when the first edition appeared in 1965; even when the fourth edition came out in 1987, few if any foresaw how quickly we would move into a world where whole genomes, not just individual genes, could be visualized and compared. There has been a comparable leap in the elucidation of protein structures as well. Thus, in the last few years, the structures of the huge molecular machines that drive the basic processes discussed in this book-DNA transcription, replication, protein synthesis, and so forth-have largely been solved at the atomic level, and many details of their inner workings revealed. The new edition of Molecular Biology of the Gene reflects these advances, and many others besides. But when we sat down to plan this latest version, we were all of a mind that much of the organization and scope of the original book should be retained. This was not a matter of convenience-inevitably, in light of the dramatic changes that had taken place since the last edition, the vast bulk of the text had to be completely rewritten anyway, and all the art rendered afresh. No, the reasoning was simply that, more than ever in this genomic era, there seemed a need for a book that explained what genes are and how they work, and this was exactly what Molecular Biology of the Gene had originally been designed to do. Thus, we have resisted the temptation to become encyclopedic or to delve into allied disciplines, such as cell biology. Also, we wanted the new edition to retain a focus on principles and concepts, another feature of its predecessors. And so we illustrate our discussion sparingly with experiments, which appear mainly in boxes. These considerations ensured the book did not become unwieldy. As stated by its author in the preface to the first edition: "Often I present a fact, and, because of lack of space, I cannot outline the experiments that demonstrate its validity. Given the choice between deleting an important principle or giving an experimental detail, I am inclined to state the principle." The current incarnation of Molecular Biology of the Gene adheres unapologetically to this philosophy. An outline of this new edition will thus be familiar to anyone who has used the book before. We begin (in Part 1 ) with a series of chapters (modified in the current edition) that place the field of molecular biology in context. These chapters summarize the history of genetics and molecul_ar biology and also present the timeless chemical principles that determine the structure and function of macromolecules. The text thereafter is organized to follow a familiar flow of topics. The nature of the genetic material, its organization and its maintenance, are discussed in Part 2 ; in addition to chapters on DNA structure, replication, recombination, and repair, new to this part of the book is a chapter on chromosomes, chromatin, and the nucleosome. This addition reflects current appreciation of how the context in which a given gene is found influences its function and regulation. NOT FOR SALE The passage of information from gene to protein- so-called gene expression - is covered in Part 3; and in Part 4 we describe the regulation of that process. As well as chapters on the basic mechanisms of gene regulation, Part 4 has chapters on the regulation of gene expression in animal development and in the evolution of animal diversity. These chapters again conform to a tradition established by earlier editions: always there has been a chapter or two linking basic mechanisms of molecular biology to pressing biological questions. In the current edition, these chapters investigate perhaps the most striking revelation to come from comparing the complete genome sequences of various animals: different animalsincluding humans-contain largely the same genes and so differences between those animals must result largely from changes in how those genes are expressed. New to the current edition is the final part-Part 5-comprising chapters on experimental methods-the techniques of molecular biology, genomics, and bioinformatics-and on the model organisms whose study has revealed many of the underlying principles of molecular biology. We alluded to the explosion in the numbers of atomic structures solved in the last few years. These include not only many of the enzymes that mediate the basic processes of molecular biology, and many of the proteins that regulate those processes, but the nucleosome as well. While it remains true that many of the basic concepts in molecular biology can be understood without reliance on structural detail- indeed it is one of the strengths of the field that this is the case-nevertheless, many mechanistic insights come only from seeing these details. Accordingly, where structures shed light on how the molecules in question work, we present them; and we do so in a consistent style throughout the book. Each part opener includes a short text, outlining what will be covered in the coming chapters, and a few photographs. These pictures, from the Cold Spring Harbor Laboratory Archive, were all taken at the Laboratory on Long Island, the great majority at the Symposium hosted there almost every summer since 1933. Captions identify who is in each picture and when it was taken. We thank Clare Bunce and the CSHL Archive for help with these. Parts of the current edition grew out of an introductory course on molecular biology taught by one of us (RL) at Harvard University, and this author is grateful to Steve Harrison and Jim Wang who contributed to this course in past years and whose influence is reflected in Chapter 6 and elsewhere. We have shown sections of the manuscript to various colleagues and their comments have been most valuable, greatly improving the accuracy and accessibility of the text and figures. Specifically we thank: Jamie Cate, Richard Ebright. Mike Eisen, Chris Fromme, Ira Hall, Adrian Krainer, Karolin Luger. Bill McGinnis, Matt Michael, Lily Mirels, Nipam Patel, Craig Peterson, Mark Ptashne, Uttam RajBhandary, and Bruce Stillman. In addition, Craig Hunter drafted the section on the worm for Chapter 21. We also thank those who provided us with figures, or the wherewithall to create them, including: Sean Carroll, Seth Darst, Edward Egelman, Georg Halder, Stuart Kim, Bill McGinnis, Steve Paddock, Phoebe Rice, Matt Scott, Peter Sorger, Andrzej Stasiak, Tom Steitz, Dan Voytas, and Steve West. We are most grateful to Leemor Joshua-Tor who rendered all the structure figures, often producing multiple versions and patiently helping us see which best �()'fe��'gA(_� needed. We are also grateful to those who provided their software1: Per Kraulis, Robert Esnouf, Ethan Merritt, and Barry Honig. Coordinates were obtained from the Protein Data Bank (www.rcsb.org/pdb/); and citations to those who solved each structure are included in the figure legends. Our art program was developed and rendered by a talented and enthusiastic team from the Dragonfly Media Group, led by Mike Demaray and Craig Durant. Renate Hellmiss helped to develop some of our initial sketches and provided early renderings of a number of figures. The cover image was rendered by Torno Narashima from an author concept sketch by Erica Beade (MBC Graphics). We thank those at Cold Spring Harbor Laboratory Press who handled development of this book. Jan Argentine, despite having to enforce the deadlines, was throughout less cajoling than she was tirelessly engaged in helping us solve the problems these presented. Maryliz Dickerson kept organized the mass of material we generated and Nora Rice helped coordinate author meetings and other aspects of the project. Denise Weiss and Ed Atkeson produced the cover design; and John Inglis, who initiated this collaboration, was on hand with advice at critical points in the process. Most of all, Kaaren Janssen, our editor, kept everything afloat with an energy, enthusiasm, and activity far beyond anything we could reasonably have asked for; things simply would not have got to this point without her. We also wish to acknowledge the work of those at Benjamin Cummings who coordinated production of the book. Frank Ruggirello oversaw the process carried out by Jim Smith, Kay Ueno. Corinne Benson, Alexandra Fellowes, Jeanne Zalesky, and Donna Kalal. Ingrid Mount at Elm Street Publishing Services coped cheerfully with the many rounds of changes to art and text even very late in the process. Michele Sordi, while part of the Benjamin Cummings team, helped bring us all together in the first place. And finally we gratefully acknowledge our families and friends who, throughout this period, provided such strong support, despite having to put up with our frequent absences and distractions.
