| crossing over in 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 in 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.

| crossing over in biology: Crossing the Boundaries of Life Karl S. Matlin, 2022-05-10 The difficulty of reconciling chemical mechanisms with the functions of whole living systems has plagued biologists since the development of cell theory in the nineteenth century. As Karl Matlin argues in Crossing the Boundaries of Life, it is no coincidence that this longstanding knot of scientific inquiry was loosened most meaningfully by the work of a cytologist, the Nobel laureate Günter Blobel. In 1975, using an experimental setup that did not contain any cells at all, Blobel was able to synthesize proteins to theorize how proteins in the cell communicate spatially, an idea he called signal hypothesis. Over the next 20 years, Blobel and other scientists were able to dissect this process into its precise molecular details. For elaborating his signal concept into a process he termed membrane topogenesis-the idea that each protein in the cell is synthesized with an address that directs the protein to its correct destination within the cell-Blobel was awarded the Nobel Prize in Physiology or Medicine in 1999. Matlin argues that Blobel's investigative strategy and its subsequent application addressed the fundamental unresolved dilemma that had bedeviled biology from its very beginning, allowing biology to overcome the barrier that had long blocked progress toward mechanistic explanations of life. Crossing the Boundaries of Life thus uses Blobel's research and life story to shed light on the importance of cell biology for twentieth-century science, illustrating how it propelled the development of adjacent disciplines like biochemistry and molecular biology-- |

| crossing over in 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 in 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 in 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 in 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. |

At the very least, you would think that if I was going to write a textbook, I should write one in an area that really needs one instead of a subject that already has multiple excellent and definitive books. So, why write this book, then? First, it's a course that I have enjoyed teaching for many years, so I am very familiar with what a student really needs to take away from this class within the time constraints of a semester. Second, because it is a course that many students take, there is a greater opportunity to make an impact on more students' pocketbooks than if I were to start off writing a book for a highly specialized upper- level course. And finally, it was fun to research and write, and can be revised easily for inclusion as part of our next textbook, High School Biology.--Open Textbook Library. |

| crossing over in biology: Neuronal and Synaptic Dysfunction in Autism Spectrum Disorder and Intellectual Disability Carlo Sala, Chiara Verpelli, 2016-04-30 Neuronal and Synaptic Dysfunction in Autism Spectrum Disorder and Intellectual Disability provides the latest information on Autism spectrum disorders (ASDs), the lifelong neurodevelopmental disorders that present in early childhood and affect how individuals communicate and relate to others and their surroundings. In addition, three quarters of ASD patients also manifest severe intellectual disability. Though certain genes have been implicated, ASDs remain largely a mystery, and research looking into causes and cellular deficits are crucial for better understanding of neurodevelopmental disorders. Despite the prevalence and insidious nature of this disorder, this book remains to be an extensive resource of information and background on the state of current research in the field. The book serves as a reference for this purpose, and discusses the crucial role synaptic activity plays in proper brain function. In addition, the volume discusses the neurodevelopmental synaptopathies and serves as a resource for scientists and clinicians in all biomedical science specialties. This research has been crucial for recent studies that have provided a rationale for the development of pharmacological agents able to counteract functional synaptic anomalies and potentially ameliorate some ASD symptoms. - Introduces the genetic and non-genetic causes of autism and associated intellectual disabilities - Describes the genes implicated in autistic spectrum disorders and their function - Considers major individual genetic causes of autism, Rett syndrome, Fragile X syndrome, and other autism spectrum disorders, as well as their classification as synaptopathies - Presents a thorough discussion of the clinical aspects of multiple neurodevelopmental disorders and the experimental models that exist to study their pathophysiology in vitro and in vivo, including animal models and patient-derived stem cell culture |
| crossing over in biology: Mechanisms in Recombination Rhoda Grell, 2012-12-06 This book contains the papers presented at the Twenty-Seventh Annual Biology Division Research Conference which was held April 1-4, 1974 in Gatlinburg, Tennessee. The topic of the symposium was Mechanisms in Recombination and it follows by exactly twenty years the previous Gatlinburg Symposium on Genetic Recombination. During this interval, and the preceding years as well, the process of recombination has remained a central and tantalizing problem for geneticists. The subject assumes added significance with the recent appeal by a committee of leading scientists for a moratorium on the construction of certain types of recombinant molecules. That autonomously replicating molecules linking portions of pro karyotic and eukaryotic DNA can now be produced in vitro attests to the technical advances that have taken place in this field. Nevertheless, the details underlying the process in vivo continue to be elusive. This symposium brought together individuals studying recombi nation in organisms as widely separated as bacteriophage and mammals and using disciplinary approaches of comparable diversity. Conse quently the present volume summarizes much of current strategies and concepts concerning the subject. The meeting was sponsored by the Biology Division of the Oak Ridge National Laboratory (operated by the Union Carbide Corporation for the U. S. Atomic Energy Commission) with the support and encour agement of its director, H. I. Adler. The organizing committee was chaired by J. K. Setlow and included R. F. Grell, R. D. Hotchkiss and E.
