| crossing-over definition biology: Phytosfere'99 - Highlights in European Plant Biotechnology Research and Technology Transfer G.E. de Vries, K. Metzlaff, 2000-11-07 Humans face the challenge of producing enough food to meet the demands imposed by economic, biological and agricultural factors: rising population; rising income; and an expectation of higher quality food and a more diverse diet; decreasing amount of land available for food production; lowering environmental impact of agricultural practices and preserving biodiversity. Biotechnology is one of the most exciting and dynamic industries of our day. It offers us the possibility of reducing our dependence on intensive farming. Plant biotechnology is central to the search for effective, environmentally safe and economically sound alternatives to the use of chemical pesticides and the exhaustion of natural resources. Today, applied plant science has four overall goals: increased crop yield, improved crop quality, reducing production costs and reducing negative environmental impact. Biotechnology is proving its value in meeting these goals. It offers farmers higher yielding crops with lower costs of production and new outlets such as nutraceuticals and crop-based bio-factories. It offers the European economy the potential of high quality, knowledge based job creation and the European consumer better quality, tastier and more nutritious food. Though there is public concern of genetic engineering, those who are close to the science understand that this is the next big frontier to be crossed. The potential and opportunities offered by plant biotechnology must not be missed. We must go forward on that basis rather than turning our backs on the science.Phytosfere'99 provides a comprehensive overview for plant biotechnology. It combines specific scientific articles, review articles and comments from outside people on it, which is unique in European Literature. |

| crossing-over definition biology: Discrete Stochastic Processes Robert G. Gallager, 2012-12-06 Stochastic processes are found in probabilistic systems that evolve with time. Discrete stochastic processes change by only integer time steps (for some time scale), or are characterized by discrete occurrences at arbitrary times. Discrete Stochastic Processes helps the reader develop the understanding and intuition necessary to apply stochastic process theory in engineering, science and operations research. The book approaches the subject via many simple examples which build insight into the structure of stochastic processes and the general effect of these phenomena in real systems. The book presents mathematical ideas without recourse to measure theory, using only minimal mathematical analysis. In the proofs and explanations, clarity is favored over formal rigor, and simplicity over generality. Numerous examples are given to show how results fail to hold when all the conditions are not satisfied. Audience: An excellent textbook for a graduate level course in engineering and operations research. Also an invaluable reference for all those requiring a deeper understanding of the subject. |
| crossing-over definition biology: A History of Genetics Alfred Henry Sturtevant, 2001 In the small “Fly Room†at Columbia University, T.H. Morgan and his students, A.H. Sturtevant, C.B. Bridges, and H.J. Muller, carried out the work that laid the foundations of modern, chromosomal genetics. The excitement of those times, when the whole field of genetics was being created, is captured in this book, written in 1965 by one of those present at the beginning. His account is one of the few authoritative, analytic works on the early history of genetics. This attractive reprint is accompanied by a website, http://www.esp.org/books/sturt/history/ offering full-text versions of the key papers discussed in the book, including the world's first genetic map. |
| crossing-over definition biology: The Concept of the Gene in Development and Evolution Peter J. Beurton, Raphael Falk, Hans-Jörg Rheinberger, 2000-05-29 Advances in molecular biological research in the latter half of the twentieth century have made the story of the gene vastly complicated: the more we learn about genes, the less sure we are of what a gene really is. Knowledge about the structure and functioning of genes abounds, but the gene has also become curiously intangible. This collection of essays renews the question: what are genes? Philosophers, historians and working scientists re-evaluate the question in this volume, treating the gene as a focal point of interdisciplinary and international research. It will be of interest to professionals and students in the philosophy and history of science, genetics and molecular biology. |
| crossing-over definition biology: The Fourth Industrial Revolution Klaus Schwab, 2017-01-03 World-renowned economist Klaus Schwab, Founder and Executive Chairman of the World Economic Forum, explains that we have an opportunity to shape the fourth industrial revolution, which will fundamentally alter how we live and work. Schwab argues that this revolution is different in scale, scope and complexity from any that have come before. Characterized by a range of new technologies that are fusing the physical, digital and biological worlds, the developments are affecting all disciplines, economies, industries and governments, and even challenging ideas about what it means to be human. Artificial intelligence is already all around us, from supercomputers, drones and virtual assistants to 3D printing, DNA sequencing, smart thermostats, wearable sensors and microchips smaller than a grain of sand. But this is just the beginning: nanomaterials 200 times stronger than steel and a million times thinner than a strand of hair and the first transplant of a 3D printed liver are already in development. Imagine “smart factories” in which global systems of manufacturing are coordinated virtually, or implantable mobile phones made of biosynthetic materials. The fourth industrial revolution, says Schwab, is more significant, and its ramifications more profound, than in any prior period of human history. He outlines the key technologies driving this revolution and discusses the major impacts expected on government, business, civil society and individuals. Schwab also offers bold ideas on how to harness these changes and shape a better future—one in which technology empowers people rather than replaces them; progress serves society rather than disrupts it; and in which innovators respect moral and ethical boundaries rather than cross them. We all have the opportunity to contribute to developing new frameworks that advance progress. |

| crossing-over definition biology: Nutrigenetics Martin Kohlmeier, 2012-12-31 Nutrigenetics: Applying the Science of Personal Nutrition provides a fully referenced, readable guide to understanding the rationale and importance of nutrigenetic applications and explains why single nutrition recommendations will not fit everybody or even a majority of modern humans. This books explains how genetic variation shapes individual nutrition requirements and sensitivities, presents questions to ask about reported gene-nutrient interactions, and what needs to be done before putting nutrigenetic tests to practical use. This book blends key concepts from the fields of genetics, biochemistry, epidemiology, public health, and clinical medicine to give a rich perspective on the genetically diverse nutritional needs and sensitivities of individuals in health and disease. A steadily increasing number of people order genetic tests to find out what they should eat for better health, well being and performance, and an even greater number asks their healthcare providers about such tests. Most of the currently offered tests are not grounded in current knowledge, often absurdly so, but few professionals can explain why they are misguided. On the other hand, there are more evidence-supported genetic variants that can guide nutrition decisions, but again most healthcare providers know little about them, much less use them in their daily practice. There is a great need for a solidly evidence-based yet accessible book that explains the science of nutrigenetics and provides the tools to evaluate new nutrigenetic tests. - Comprehensive coverage of the emerging science of nutritional genetics and its promise for individually tailored nutrition guidance - Presents practical examples to enhance comprehension and spur additional research - Offers a logical progression from what nutrigenetics is, to its possibilities in enhancing health |
| crossing-over definition biology: Molecular Biology Nancy Craig, Rachel Green, Orna Cohen-Fix, Carol Greider, Gisela Storz, Cynthia Wolberger, 2014-05 The biological world operates on a multitude of scales - from molecules to tissues to organisms to ecosystems. Throughout these myriad levels runs a common thread: the communication and onward passage of information, from cell to cell, from organism to organism and ultimately, from generation to generation. But how does this information come alive to govern the processes that constitute life? The answer lies in the molecular components that cooperate through a series of carefully-regulated processes to bring the information in our genome to life. These components and processes lie at the heart of one of the most fascinating subjects to engage the minds of scientists today: molecular biology. Molecular Biology: Principles of Genome Function, Second Edition, offers a fresh approach to the teaching of molecular biology by focusing on the commonalities that exist between the three kingdoms of life, and discussing the differences between the three kingdoms to offer instructive insights into molecular processes and components. This gives students an accurate depiction of our current understanding of the conserved nature of molecular biology, and the differences that underpin biological diversity. Additionally, an integrated approach demonstrates how certain molecular phenomena have diverse impacts on genome function by presenting them as themes that recur throughout the book, rather than as artificially separated topics As an experimental science, molecular biology requires an appreciation for the approaches taken to yield the information from which concepts and principles are deduced. Experimental Approach panels throughout the text describe research that has been particularly valuable in elucidating difference aspects of molecular biology. Each panel is carefully cross-referenced to the discussion of key molecular biology tools and techniques, which are presented in a dedicated chapter at the end of the book. Molecular Biology further enriches the learning experience with full-color artwork, end-of-chapter questions and summaries, suggested further readings grouped by topic, and an extensive glossary of key terms. Features: A focus on the underlying principles of molecular biology equips students with a robust conceptual framework on which to build their knowledge An emphasis on their commonalities reflects the processes and components that exist between bacteria, archae, and eukaryotes Experimental Approach panels demonstrate the importance of experimental evidence by describing research that has been particularly valuable in the field |
| crossing-over definition biology: Why Evolution is True Jerry A. Coyne, 2010-01-14 For all the discussion in the media about creationism and 'Intelligent Design', virtually nothing has been said about the evidence in question - the evidence for evolution by natural selection. Yet, as this succinct and important book shows, that evidence is vast, varied, and magnificent, and drawn from many disparate fields of science. The very latest research is uncovering a stream of evidence revealing evolution in action - from the actual observation of a species splitting into two, to new fossil discoveries, to the deciphering of the evidence stored in our genome. Why Evolution is True weaves together the many threads of modern work in genetics, palaeontology, geology, molecular biology, anatomy, and development to demonstrate the 'indelible stamp' of the processes first proposed by Darwin. It is a crisp, lucid, and accessible statement that will leave no one with an open mind in any doubt about the truth of evolution. |

| crossing-over definition biology: Multiple Representations in Biological Education David F. Treagust, Chi-Yan Tsui, 2013-02-01 This new publication in the Models and Modeling in Science Education series synthesizes a wealth of international research on using multiple representations in biology education and aims for a coherent framework in using them to improve higher-order learning. Addressing a major gap in the literature, the volume proposes a theoretical model for advancing biology educators’ notions of how multiple external representations (MERs) such as analogies, metaphors and visualizations can best be harnessed for improving teaching and learning in biology at all pedagogical levels. The content tackles the conceptual and linguistic difficulties of learning biology at each level—macro, micro, sub-micro, and symbolic, illustrating how MERs can be used in teaching across these levels and in various combinations, as well as in differing contexts and topic areas. The strategies outlined will help students’ reasoning and problem-solving skills, enhance their ability to construct mental models and internal representations, and, ultimately, will assist in increasing public understanding of biology-related issues, a key goal in today’s world of pressing concerns over societal problems about food, environment, energy, and health. The book concludes by highlighting important aspects of research in biological education in the post-genomic, information age. |
| crossing-over definition biology: Evolution of Translational Omics Institute of Medicine, Board on Health Sciences Policy, Board on Health Care Services, Committee on the Review of Omics-Based Tests for Predicting Patient Outcomes in Clinical Trials, 2012-09-13 Technologies collectively called omics enable simultaneous measurement of an enormous number of biomolecules; for example, genomics investigates thousands of DNA sequences, and proteomics examines large numbers of proteins. Scientists are using these technologies to develop innovative tests to detect disease and to predict a patient's likelihood of responding to specific drugs. Following a recent case involving premature use of omics-based tests in cancer clinical trials at Duke University, the NCI requested that the IOM establish a committee to recommend ways to strengthen omics-based test development and evaluation. This report identifies best practices to enhance development, evaluation, and translation of omics-based tests while simultaneously reinforcing steps to ensure that these tests are appropriately assessed for scientific validity before they are used to guide patient treatment in clinical trials. |
