The nucleus guides the life processes of the cell by directing cellular reproduction, differentiation during development, and metabolism. The study of the structure and function of the nucleus along with its genetic material serves as the foundation for the science of genetics. Principles of Nuclear Structure and Function provides a comprehensive overview of the cell nucleus by illustrating the connection between function and the architecture of the nucleus. Richly illustrated throughout, each chapter includes an overview, detailed examples, summary points, references, and callout boxes highlighting methods and cutting-edge technology. The appendix provides a useful list of related Web sites. Some of the subjects reviewed within Principles of Nuclear Structure and Function include: * Nuclear structure, replication, damage, and repair * Regulation of gene expression * The cell cycle * Meiosis and recombination This timely volume presents functional studies within their proper structural context and is an informative profile of the cell and molecular biology in nuclei and chromatin. For those studying cell biology, along with molecular and cell biologists, geneticists, and reproductive biologists, Principles of Nuclear Structure and Function is a definitive resource.

Aspects of Nuclear Structure and Function deals with various aspects of nuclear structure and function and covers topics ranging from the ultrastructure of the female gamete to the structure, biochemistry, and functions of the nuclear envelope. Banding patterns in chromosomes, histones and nonhistone proteins, and the transfer of genetic information in polytene cells are also discussed. This book is comprised of six chapters and begins by presenting a comparative view of some aspects of the ultrastructure of the vegetative (growth) aspects of oogenesis, with emphasis on microtubules, intercellular bridges of differentiating oocytes, and vitellogenesis as well as accessory structures of the egg envelope. The following chapters explore the structure, biochemistry, and functions of the nuclear envelope; banding patterns in chromosomes; chromosomal proteins (histones and nonhistone proteins); transfer of genetic information in polytene cells; and the intracellular biology of DNA polymerases in eukaryotic cells, their association with the nucleus, and how this association changes during the mitotic cell cycle. The relationship between eukaryotic DNA polymerases and DNA replication is also examined. This monograph should be a valuable resource for biochemists.

Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.

The nucleus is the most prominent structure in eukaryotic cells. It houses the cell's DNA and is the hub for DNA replication, transcription, and RNA processing. Despite its prominence and importance, our understanding of how the nucleus and its DNA are organized in space and time--and the implications of that organization for proper function--has lagged behind that of other cellular structures. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology covers recent advances in our understanding of nuclear organization and function. The contributors discuss the 3D organization of chromatin, the various nuclear bodies and compartments that have been identified, and the roles of RNA and actin in shaping nuclear organization, as well as how these structures interact with each other and with peripheral features (e.g., the nuclear pore complex and inner nuclear membrane proteins) to carry out the work of the nucleus. Insights into DNA replication timing and RNA processing dynamics based on new technologies aimed at examining chromatin and other intranuclear structures at high resolution are also included. Multiple chapters are devoted to physiological and disease processes involving disruption of nuclear structure and function (e.g., viral infection). This volume is therefore essential reading for all cell and molecular biologists, as well as pathologists interested in the role of nuclear architecture in disease.

Nuclear structure Physics connects to some of our fundamental questions about the creation of universe and its basic constituents. At the same time, precise knowledge on the subject has lead to develop many important tools of human kind such as proton therapy, radioactive dating etc. This book contains chapters on some of the crucial and trending research topics in nuclear structure, including the nuclei lying on the extremes of spin, isospin and mass. A better theoretical understanding of these topics is important beyond the confines of the nuclear structure community. Additionally, the book will showcase the applicability and success of the different nuclear effective interaction parameters near the drip line, where hints for level reordering have already been seen, and where one can test the isospin-dependence of the interaction. The book offers comprehensive coverage of the most essential topics, including: • Nuclear Structure of Nuclei at or Near Drip-Lines • Synthesis challenges and properties of Superheavy nuclei • Nuclear Structure and Nuclear models - Ab-initio calculations, cluster models, Shell-model/DSM, RMF, Skyrme • Shell Closure, Magicity and other novel features of nuclei at extremes • Structure of Toroidal, Bubble Nuclei, halo and other exotic nuclei These topics are not only very interesting from theoretical nuclear physics perspective but are also quite complimentary for ongoing nuclear physics experimental program worldwide. It is hoped that the book chapters written by experienced and well known researchers/experts will be helpful for the master students, graduate students and researchers and serve as a standard & uptodate research reference book on the topics covered.

The principal goals of the study were to articulate the scientific rationale and objectives of the field and then to take a long-term strategic view of U.S. nuclear science in the global context for setting future directions for the field. Nuclear Physics: Exploring the Heart of Matter provides a long-term assessment of an outlook for nuclear physics. The first phase of the report articulates the scientific rationale and objectives of the field, while the second phase provides a global context for the field and its long-term priorities and proposes a framework for progress through 2020 and beyond. In the second phase of the study, also developing a framework for progress through 2020 and beyond, the committee carefully considered the balance between universities and government facilities in terms of research and workforce development and the role of international collaborations in leveraging future investments. Nuclear physics today is a diverse field, encompassing research that spans dimensions from a tiny fraction of the volume of the individual particles (neutrons and protons) in the atomic nucleus to the enormous scales of astrophysical objects in the cosmos. Nuclear Physics: Exploring the Heart of Matter explains the research objectives, which include the desire not only to better understand the nature of matter interacting at the nuclear level, but also to describe the state of the universe that existed at the big bang. This report explains how the universe can now be studied in the most advanced colliding-beam accelerators, where strong forces are the dominant interactions, as well as the nature of neutrinos.
