Download or read book Functional Organization of the Plant Nucleus written by Iris Meier and published by Springer. This book was released on 2010-11-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a presentation to the Linnean Society of London in November 1831, the Scottish botanist Robert Brown (perhaps better known for his discovery of Brownian motion) mentioned almost as an afterthought that in orchid epidermal cells, a single “circular areola” could be seen, a “nucleus of the cell as perhaps it might be termed.” Thus, the term “nucleus” (from Latin nucleus or nuculeus, “little nut” or kernel) was born for the compartment of the eukaryotic cell that contains the maj- ity of genetic information. One hundred and seventy-seven years later, we know that the nucleus is the site where genetic information is stored in the form of DNA, and where it is protected from damage, duplicated, divided, recombined, repaired, and “expressed.” For the latter, the genetic information is faithfully transcribed from DNA to RNA, then released from the nucleus into the surrounding cytoplasm. Most likely translated into polypeptide chains, the information re-enters the nucleus in the form of diverse proteins that function in the processes listed above.
Download or read book Calcium and Calmodulin Function in the Cell Nucleus written by Oriol Bachs and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the role of calcium and calmodulin in the cell nucleus. Calcium, which is an important second messenger of signal transduction pathways, can also operate in the cell nucleus. Different calcium binding proteins, which are the targets of cellular calcium, have been identified in the nucleus of many different cell types. Prominent among these calcium binding proteins is calmodulin, which appears to be involved in the regulation of major nuclear functions such as gene expression and DNA replication.
Download or read book The Nucleus Second Edition written by Ana Pombo and published by . This book was released on 2021-09 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Oogenesis written by Leon W. Browder and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book launches a new continuing series in developmental biology. Any new publishing venture in science can only be justified if it satisfies a need and fulfills that need in an exemplary way. I believe that there is an acute need for comprehensive treatises on specialized topics in developmental biology-especially because this is a very diverse field that receives con tributions from a wide variety of disciplines. It is difficult to remain abreast of progress in multifaceted topics and to understand how the various aspects of a topic interrelate. The volumes that will comprise this series are designed to facilitate those processes. Each volume of this series will attempt to convey the current status of research and thought on a specific topic in development, place current research within historical perspective, and lay the intellectual groundwork for future research. These volumes are intended to provide an in-depth background on these topics for advanced undergraduates, graduate stu dents, and senior scientists. An investigator considering research in one of these areas will get an overview of the field as well as discover the status of recent research in the area.

Download or read book The Functional Nucleus written by David P. Bazett-Jones and published by Springer. This book was released on 2018-06-23 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives an in-depth overview on nuclear structure and function. It clearly shows that the epigenome and the three-dimensional organization of the nucleus are not independent properties. The intimate relationship between the location and the epigenetic modifications of gene loci is highlighted. Finally, it shows that the complex three-dimensional organization of the nucleus is not just of academic interest: The structure, composition and function of virtually all of the sub-nuclear compartments identified so far can be implicated to a list of human genetic diseases. Hence, a detailed elucidation of how these domains are assembled and function will provide new opportunities for therapeutic intervention in clinical practice.

Download or read book Epigenetics Nuclear Organization Gene Function written by John C. Lucchesi and published by Oxford University Press. This book was released on 2018-12-19 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epigenetics is the study of heritable changes in gene function that do not involve changes in the DNA sequence. These changes, consisting principally of DNA methylation, histone modifications, and non-coding RNAs, maintain or modulate the initial impact of regulatory factors that recognize and associate with particular genomic sequences. Epigenetic modifications are manifest in all aspects of normal cellular differentiation and function, but they can also have damaging effects that result in pathologies such as cancer. Research is continuously uncovering the role of epigenetics in a variety of human disorders, providing new avenues for therapeutic interventions and advances in regenerative medicine. This book's primary goal is to establish a framework that can be used to understand the basis of epigenetic regulation and to appreciate both its derivation from genetics and interdependence with genetic mechanisms. A further aim is to highlight the role played by the three-dimensional organization of the genetic material itself (the complex of DNA, histones and non-histone proteins referred to as chromatin), and its distribution within a functionally compartmentalized nucleus. This architectural organization of the genome plays a major role in the subsequent retrieval, interpretation, and execution of both genetic and epigenetic information.
Download or read book Integrated Neuroscience written by Elliott M. Marcus and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook takes as a premise that, in order to make intelligent diagnosis and provide a rational treatment in disorders of the nervous system, it is necessary to develop the capacity to answer the basic questions of clinical neurology: (1) Where is the disease process located? (2) What is the nature of the disease process? The purpose of this textbook is to enable the medical student to acquire the basic information of the neurosciences and neurology and most importantly the ability to apply that information to the solution of clinical problems. The authors also suggest that hospital trips be a part of any Clinical Neurosciences Course so that the student can put into actual practice what he has learned in the classroom. We believe that this textbook will be of value to the student throughout the four years of the medical school curriculum. Medical, psychiatry and neurology residents may also find this text of value as an introduction or review.
