Download or read book Centromere written by Durdica Ugarkovic and published by Springer Science & Business Media. This book was released on 2009-06-12 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The centromere is a chromosomal region that enables the accurate segregation of chromosomes during mitosis and meiosis. It holds sister chromatids together, and through its centromere DNA–protein complex known as the kinetochore binds spindle microtubules to bring about accurate chromosome movements. Despite this conserved function, centromeres exhibit dramatic difference in structure, size, and complexity. Extensive studies on centromeric DNA revealed its rapid evolution resulting often in significant difference even among closely related species. Such a plasticity of centromeric DNA could be explained by epigenetic c- trol of centromere function, which does not depend absolutely on primary DNA sequence. According to epigenetic centromere concept, which is thoroughly d- cussed by Tanya Panchenko and Ben Black in Chap. 1 of this book, centromere activation or inactivation might be caused by modifications of chromatin. Such acquired chromatin epigenetic modifications are then inherited from one cell di- sion to the next. Concerning centromere-specific chromatin modification, it is now evident that all centromeres contain a centromere specific histone H3 variant, CenH3, which replaces histone H3 in centromeric nucleosomes and provides a structural basis that epigenetically defines centromere and differentiates it from the surrounding chromatin. Recent insights into the CenH3 presented in this chapter add important mechanistic understanding of how centromere identity is initially established and subsequently maintained in every cell cycle.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest advances concerning the regulation of chromosome segregation during cell division by means of centromeres and kinetochores. The authors cover both state-of-the-art techniques and a range of species and model systems, shedding new light on the molecular mechanisms controlling the transmission of genetic material between cell divisions and from parent to offspring. The chapters cover five major areas related to the current study of centromeres and kinetochores: 1) their genetic and epigenetic features, 2) key breakthroughs at the molecular, proteomic, imaging and biochemical level, 3) the constitutive centromere proteins, 4) the role of centromere proteins in the physical process of chromosome segregation and its careful orchestration through elaborate regulation, and 5) intersections with reproductive biology, human health and disease, as well as chromosome evolution. The book offers an informative and provocative guide for newcomers as well as those already acquainted with the field.

Download or read book The Centromere written by K. H. Andy Choo and published by Oxford University Press, USA. This book was released on 1997 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The centromere is an essential structure on all eukaryotic chromosomes that allows the equipartition of chromosomes during mitotic and meiotic cell divisions. Since its cytogenetic recognition as a constructed part of a chromosome many decades ago, great advances have been made in ourunderstanding of this intriguing structure, especially at the molecular level. This book brings together all available information on the centromere. It covers in details the DNA and protein components of this structure, and their individual functions, in species as diverse as budding and fissionyeasts, nematodes, Drosophila, mice, and humans; newly discovered roles of the centromere in marshalling "passenger" proteins; important emerging concepts such as latent centromeres and epigenetic factors; cytogenetic problems associated with centromere abnormalities; and practical application ofcentromere studies, such as in the construction of human artificial chromosomes for gene therapy. Supported by ample illustrations, the book is written with sufficient simplicity and detail to suit both specialist and non-specialist scholars. It is the first book on the subject

Available in PDF, EPUB and Kindle. Book excerpt: Chromatin Regulation and Dynamics integrates knowledge on the dynamic regulation of primary chromatin fiber with the 3D nuclear architecture, then connects related processes to circadian regulation of cellular metabolic states, representing a paradigm of adaptation to environmental changes. The final chapters discuss the many ways chromatin dynamics can synergize to fundamentally contribute to the development of complex diseases. Chromatin dynamics, which is strategically positioned at the gene-environment interface, is at the core of disease development. As such, Chromatin Regulation and Dynamics, part of the Translational Epigenetics series, facilitates the flow of information between research areas such as chromatin regulation, developmental biology, and epidemiology by focusing on recent findings of the fast-moving field of chromatin regulation. Presents and discusses novel principles of chromatin regulation and dynamics with a cross-disciplinary perspective Promotes crosstalk between basic sciences and their applications in medicine Provides a framework for future studies on complex diseases by integrating various aspects of chromatin biology with cellular metabolic states, with an emphasis on the dynamic nature of chromatin and stochastic principles Integrates knowledge on the dynamic regulation of primary chromatin fiber with 3D nuclear architecture, then connects related processes to circadian regulation of cellular metabolic states, representing a paradigm of adaptation to environmental changes

Download or read book Neurospora written by Rowland H. Davis and published by Oxford University Press. This book was released on 2000-08-17 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will serve as the definitive reference work on the basic physiology, biochemistry, development, genetics, and molecular biology of Neurospora, together with a description of basic laboratory methods. Among the filamentous fungi, Neurospora is a basic model organism, used initially in the establishment of the one-gene, one-enzyme principle, and it has become a favored research organism in a variety of biological problems since that time. Until now, there has been no standard guide to the organism. The book reviews early research since 1927 and describes the current state of the major research programs now being pursued. Each chapter includes detailed literature references for the scholar and experimentalist. Both researchers in the filamentous fungi and biologists requiring information about Neurospora will find this an invaluable resource because it gathers 75 years of scattered research literature into a coherent account.
