This volume and its companion, Volume 339, supplement Volumes 176, 177, 239, and 261. Chapters are written with a "hands-on" perspective. That is, practical applications with critical evaluations of methodologies and experimental considerations needed to design, execute, and interpret NMR experiments pertinent to biological molecules.

Cell Biology, A Comprehensive Treatise, Volume 3: Gene Expression: The Production of RNA's mainly discusses the molecular and cytological bases of gene expression. The coverage begins with the concepts of organization of DNA and gene sequences in chromosomes, as an introduction to a more detailed coverage of gene expression. The book opens with a general discussion on the organization of DNA sequences in chromosomes. This chapter includes different methods of analyzing DNA sequences. As the book progresses, it looks upon the details on gene reiteration and amplification up to the transcription of prokaryotes and eukaryotes. It includes the ways of regulating transcription. The following chapters deal mostly with the structure and activity of genes up to the different virus strains in both RNA and DNA. The cytoplasmic and environmental impact on gene expression is also discussed. Chapter 8 generally tackles the DNA conformation and template function. The succeeding chapters focus on the transfer and ribosomal RNA as a result of maturation events; the processing of hnRNA and its relation to mRNA; and recombinant DNA procedures. The book closes with the directory of the different classes of cellular RNAs. This book will be helpful to many graduate students, teachers, scientists, and researchers in need of information regarding cell biology.

The Molecular Biology of the Bacilli, Volume I: Bacillus subtilis focuses on areas of research traditionally investigated in Bacillus subtilis, as well as topics in which outstanding progress has been made. It discusses the sporulation, defective bacteriophage, and transformation of Bacillus subtilis. Organized into 11 chapters, the book begins with the genetic map of Bacillus subtilis, followed by DNA replication and RNA polymerase of the said species. The book then describes the translational apparatus of Bacillus subtilis. It also explains the genetic transformation in Bacillus subtilis; the sporulation genes; the regulatory mechanisms in the development of lytic bacteriophages in this species; the temperate Bacillus subtilis phages; the specialized transduction in Bacillus subtilis; and molecular cloning in this organism. Lastly, the book considers the most economically important areas of the microbiological industry employing bacilli, including the production of enzymes, nucleosides, riboflavin, and preparations pathogenic to insects. This book will be useful to scientists who are concerned with the use of Bacillus subtilis as a tool for the study of molecular biology and to those who wish to increase the medical, veterinary, and industrial usefulness of this and related organisms.

This volume is the third in the series devoted to Antibiotics initiated by Springer Verlag in 1967. The first two volumes were devoted to the Mode of Action of Antibiotics and Biogenesis, respectively and were received graciously. During the intervening years these two works have been used often by research workers and students alike and have been quoted extensively. Although a number of other excellent treatises on antibiotics have appeared, the Springer series has set a standard for thoroughness and quality that meets the need of the scientific community. It is against this background that the present Editors set about the preparation of a third volume in the Series on Antibiotics. Since the appearance of Volume I, also dealing with Mechanism of Action, tremendous strides have been made in the depth and breadth of our knowledge of molecular biology, microbial chemistry and molecular pharmacology and of their direct application to studies on the mode of action of drugs. The field of molecular biology itself was in its relative infancy during the preceding decade and the unique role played by many anti biotics in the development of our understanding of nucleic acid synthesis and function and its relationship to protein synthesis and cell physiology has led rapidly to a very precise, understanding of how many of these same antibiotics inhibit susceptible cells.

The Cell Nucleus, Volume III focuses mainly on nucleic acids, nuclear proteins, and special aspects of nuclear functions. This volume particularly discusses the organization of bacterial and viral DNA, as well as the nuclear DNA of eukaryotic organisms. It also describes nuclear DNA polymerases, precursors of messenger RNA, ribonucleoproteins, and nuclear high- and low-molecular-weight RNAs. Furthermore, this volume looks into the two broad classes of nuclear proteins: histones and nonhistone proteins. It also presents advances made in the knowledge of mammalian DNA-dependent RNA polymerase, cytochemical detection of nuclear enzymes, and nuclear protein synthesis. Moreover, it elucidates the effects of female steroid hormones on target cell nuclei, describes the nucleus during avian erythropoiesis, and reports the general properties of intranuclear viruses.
