Download or read book The Origin and Evolution of Eukaryotes written by Patrick J. Keeling and published by . This book was released on 2014 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: All protists, fungi, animals, and plants on Earth are eukaryotes. Their cells possess membrane-bound organelles including a nucleus and mitochondria, distinct cytoskeletal features, and a unique chromosome structure that permits them to undergo mitosis or meiosis. The emergence of eukaryotic cells from prokaryotic ancestors about 2 billion years ago was a pivotal evolutionary transition in the history of life on Earth. But the change was abrupt, and few clues exist as to the nature of the intermediate stages. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology examines evolutionary scenarios that likely led to the emergence and rapid evolution of eukaryotes. Contributors review the mechanisms, timing, and consequences of endosymbiosis, as well as molecular and biochemical characteristics of archaea and bacteria that may have contributed to the first eukaryotic lineage. They explore all of the available evidence, including clues from the fossil record and comparative genomics, and formulate ideas about the origin of genomic characteristics (e.g., chromatin and introns) and specific cellular features (e.g., the endomembrane system) in eukaryotes. Topics such as the origins of multicellularity and sex are also covered. This volume includes discussion of multiple evolutionary models that warrant serious attention, as well as lively debate on some of the most contentious topics in the field. It will thus be fascinating reading for evolutionary biologists, cell and molecular biologists, paleobiologists, and all who are interested in the history of life on Earth.
Download or read book Transcriptional Regulation in Eukaryotes written by Michael F. Carey and published by CSHL Press. This book was released on 2000 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the genome era, the analysis of gene expression has become a critical requirement in many laboratories. But there has been no comprehensive source of strategic, conceptual, and technical information to guide this often complex task. Transcriptional Regulation in Eukaryotes answers that need. Written by two experienced investigators, Michael Carey and Stephen Smale at the UCLA School of Medicine, and based in part on the Gene Expression course taught at Cold Spring Harbor Laboratory, this book directly addresses all the concerns of a laboratory studying the regulation of a newly isolated gene and the biochemistry of a new transcription factor. This important and unique book is essential reading for anyone pursuing the analysis of gene expression in model systems or disease states.
Download or read book Plasmids of Eukaryotes written by Karl Esser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possession of plasmids was for a long time recognized only in the bacteria. It is now evident that plasmids, or replicative forms of DNA structurally and experimentally comparable to bacterial plasmids, exist in eukaryotic organisms as well. Such plasmids are in fact common among fungi and higher plants. The present review is undertaken to provide a comprehensive account of the data available on plasmids found in eukaryotic organisms. This review will not consider plasmids of prokaryotic origin, even though certain bacterial plasmids, such as the tumor-inducing (Ti) plasmids of Agrobacterium tumefaciens, may be intimately associated with transformation of the eukaryotic host. This book, moreover, does not consider transformation experiments in eukaryotic hosts involving viral DNA as vectors, although indeed such vectors have been developed for use in plant and animal systems. After a general introduction, providing historical perspective on the nature and role of plasmids, a list of eukaryotic plasmids will be presented according to their origin. This is followed by a detailed discussion of known structure and function. In subsequent chapters the practical implications of eukaryotic plasmids for molecular cloning and biotechnology will be discussed. This latter part traces the development of interest'in biotechnical genetics and gives special consideration to the use of eukaryotic systems for gene cloning. The terminology biotechni cal genetics is introduced to the reader and is used in a general sense as equivalent to genetic engineering. Biotechnical genetics includes, but is not limited to, gene cloning through recombinant DNA technology.

Download or read book Concepts of Biology written by Samantha Fowler and published by . This book was released on 2018-01-07 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Download or read book Reproduction of Eukaryotic Cells written by David M. Prescott and published by Elsevier. This book was released on 2012-12-02 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproduction of Eukaryotic Cells organizes in a single source the principal facts and observations on the cell life cycle and reproduction of eukaryotic cells. The aim is to increase the overall understanding of how these cells reproduce themselves and how this reproduction is regulated. The book begins with a discussion of the sections of the cell cycle and regulation of cell reproduction. Separate chapters on cell growth, cell synchrony, the G1 period, S period, and G2 period follow. Subsequent chapters are devoted to activities during cell division; cell cycle changes in surface morphology; the role of cyclic AMP (cAMP) and cyclic GMP (cGMP) in regulation of cell reproduction; and changes in nuclear proteins, RNA synthesis, and enzyme activities during the cell cycle. The final chapter covers the genetic analysis of the cell cycle.
Download or read book Mitochondria and Anaerobic Energy Metabolism in Eukaryotes written by William F. Martin and published by Walter de Gruyter GmbH & Co KG. This book was released on 2020-12-07 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mitochondria are sometimes called the powerhouses of eukaryotic cells, because mitochondria are the site of ATP synthesis in the cell. ATP is the universal energy currency, it provides the power that runs all other life processes. Humans need oxygen to survive because of ATP synthesis in mitochondria. The sugars from our diet are converted to carbon dioxide in mitochondria in a process that requires oxygen. Just like a fire needs oxygen to burn, our mitochondria need oxygen to make ATP. From textbooks and popular literature one can easily get the impression that all mitochondria require oxygen. But that is not the case. There are many groups of organismsm known that make ATP in mitochondria without the help of oxygen. They have preserved biochemical relicts from the early evolution of eukaryotic cells, which took place during times in Earth history when there was hardly any oxygen avaiable, certainly not enough to breathe. How the anaerobic forms of mitochondria work, in which organisms they occur, and how the eukaryotic anaerobes that possess them fit into the larger picture of rising atmospheric oxygen during Earth history are the topic of this book.

Download or read book Secret Chambers written by M. D. Brasier and published by Oxford University Press. This book was released on 2012-05-31 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The appearance of the modern plant cell is one of the most deeply puzzling and unlikely steps in the whole history of life, and as Martin Brasier shows in Secret Chambers, decoding this puzzle has been a great adventure that has mainly taken place over the last fifty years. Covering the period from 1 to 2 billion years ago, Brasier presents the modern understanding of the origin of the complex cell, without which there would be nothing on Earth today except bacteria. Indeed, the formation of this cell was a fundamental turning point in the history of life on Earth. Weaving together several threads, Brasier highlights the importance of single-celled forms to marine ecosystems, describes symbiosis and coral reefs, and examines the architecture and beauty of single-celled Foraminifera and what they tell us about evolution. Throughout the book, he interweaves cutting-edge scientific discussions with lively descriptions of his explorations around the world, from the Caribbean Sea and the Egyptian pyramids, to the shores of the great lakes in Canada, and to the reefs and deserts of Australia.

Download or read book Genomics and Evolution of Microbial Eukaryotes written by Laura Katz Olson and published by Oxford University Press, USA. This book was released on 2006-09-07 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents a unique combination of recently-emerged information on eukaryotic microbes, evolution and genomics. Eukaryotes, cells with nuclei, evolved as microbes and have existed on Earth for approximately 2 billion years. Although currently relatively understudied, eukaryotic microorganisms are of critical importance to ecosystems (through their involvement in global biogeochemical cycles), human health (they include some of the deadliest pathogens), and our desire tounderstand global biodiversity. Recent advances, particularly in DNA sequencing technologies, are making eukaryotic microbes more accessible through genome analyses. Insights from these studies are challenging previously held theories of genome evolution, based on studies of a limited number of plants,animals and fungi.
Download or read book Cellular Interactions written by H. F. Linskens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 761 pages. Available in PDF, EPUB and Kindle. Book excerpt: H. F. LINSKENS and J. HESLOP-HARRISON The chapters of this volume deal with intercellular interaction phenomena in plants. Collectively they provide a broad conspectus of a highly active, if greatly fragmented, research field. Certain limitations have been imposed on the subject matter, the most impor tant being the exclusion of long-range interactions within the plant body. It is true that pervasive hormonal control systems cannot readily be demarcated from controls mediated by pheromones or information-carrying molecules with more limited spheres of action, but consideration is given in this volume to the main classes of plant hormones and their functions only incidentally, since these are treated adequately in other volumes of this Encyclopedia series (V - ume 9-11) and in numerous other texts and reviews. Similarly, certain other effects, such as those associated with nutrients and ions, are not considered in any detail. Furthermore, we have excluded intracellular interactions, and also consideration of transport phenomena, which are treated in detail in Vol ume 3 of this Series. Other aspects of inter-cellular interaction, such as cell surface phenomena and implications of lectin-carbohydrate interactions, and plant-virus inter-relationships, are treated in other sections of this Encyclopedia (Volumes 13B and 14B, respectively). In the volume on physiological plant pathology (Volume 4 of this series) special attention has been given to host pathogen interaction. These aspects of our subject will therefore be excluded in the present treatise.
