Download or read book Evolution by Gene Duplication written by Susumu Ohno and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is said that "necessity is the mother of invention". To be sure, wheels and pulleys were invented out of necessity by the tenacious minds of upright citi zens. Looking at the history of mankind, however, one has to add that "Ieisure is the mother of cultural improvement". Man's creative genius flourished only when his mind, freed from the worry of daily toils, was permitted to entertain apparently useless thoughts. In the same manner, one might say with regard to evolution that "natural selection mere(y tnodifted, while redundanry created". Natural selection has been extremely effective in policing alleHe mutations which arise in already existing gene loci. Because of natural selection, organisms have been able to adapt to changing environments, and by adaptive radiation many new species were created from a common ancestral form. Y et, being an effective policeman, natural selection is extremely conservative by nature. Had evolution been entirely dependent upon natural selection, from a bacterium only numerous forms of bacteria would have emerged. The creation of metazoans, vertebrates and finally mammals from unicellular organisms would have been quite impos sible, for such big leaps in evolution required the creation of new gene loci with previously nonexistent functions. Only the cistron which became redun dant was able to escape from the relentless pressure of natural selection, and by escaping, it accumulated formerly forbidden mutations to emerge as a new gene locus.

Download or read book Evolution after Gene Duplication written by Katharina Dittmar and published by John Wiley & Sons. This book was released on 2011-06-09 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene duplication has long been believed to have played a major role in the rise of biological novelty through evolution of new function and gene expression patterns. The first book to examine gene duplication across all levels of biological organization, Evolution after Gene Duplication presents a comprehensive picture of the mechanistic process by which gene duplication may have played a role in generating biodiversity. Key Features: Explores comparative genomics, genome evolution studies and analysis of multi-gene families such as Hox, globins, olfactory receptors and MHC (immune system) A complete post-genome treatment of the topic originally covered by Ohno's 1970 classic, this volume extends coverage to include the fate of associated regulatory pathways Taps the significant increase in multi-gene family data that has resulted from comparative genomics Comprehensive coverage that includes opposing theoretical viewpoints, comparative genomics data, theoretical and empirical evidence and the role of bioinformatics in the study of gene duplication This up-to-date overview of theory and mathematical models along with practical examples is suitable for scientists across various levels of biology as well as instructors and graduate students.

Download or read book Doubling and Duplicating in the Book of Genesis written by Elizabeth R. Hayes and published by Penn State Press. This book was released on 2016-08-25 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The style of the Hebrew Bible has long been of significant interest to scholars and exegetes alike. Early Jewish and later Christian commentaries point out the importance of the exact wording in interpreting the text, and many an article has been written on features such as repetition and inclusio. With the rise of literary and narrative criticism in biblical studies, these features have received even more attention. The current book stands in the tradition of Robert Alter in that it focuses on how the text of Genesis is written and phrased. More explicitly, it is interested in why Genesis is formulated the way it is and how this affects the reader in his/her encounter with the text. Doubling and Duplicating is not only concerned with a style-as-analysis frame for interpreters but also with its role as a guide for any audience and its gateway to the ancient mind-set (ideological, ontological, and so on). All of the contributors to this collected volume focus on the form of the book of Genesis—that is, on its use of language and formulation. Yet, each author does this in his/her own way, depending on the most fitting tool for the specific research question or based on the researcher’s methodological background. Thus, the essays represent the various approaches in current literary and stylistic criticism as applied to the biblical corpus. Furthermore, the recurring duality of the features discussed in each of the contributions adds to the overall unity of the volume. This recurrence suggests the presence of a stylistic feature in the book of Genesis, the feature of doubling and duplicating, that surpasses the other features of the individual units or stories. This book offers insights about meaning-making on both the micro- and the macro-text levels.

Download or read book Gene Duplication written by Felix Friedberg and published by BoD – Books on Demand. This book was released on 2011-10-21 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book Gene Duplication consists of 21 chapters divided in 3 parts: General Aspects, A Look at Some Gene Families and Examining Bundles of Genes. The importance of the study of Gene Duplication stems from the realization that the dynamic process of duplication is the "sine qua non" underlying the evolution of all living matter. Genes may be altered before or after the duplication process thereby undergoing neofunctionalization, thus creating in time new organisms which populate the Earth.

Download or read book Patterns in Permutations and Words written by Sergey Kitaev and published by Springer Science & Business Media. This book was released on 2011-08-30 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been considerable interest recently in the subject of patterns in permutations and words, a new branch of combinatorics with its roots in the works of Rotem, Rogers, and Knuth in the 1970s. Consideration of the patterns in question has been extremely interesting from the combinatorial point of view, and it has proved to be a useful language in a variety of seemingly unrelated problems, including the theory of Kazhdan—Lusztig polynomials, singularities of Schubert varieties, interval orders, Chebyshev polynomials, models in statistical mechanics, and various sorting algorithms, including sorting stacks and sortable permutations. The author collects the main results in the field in this up-to-date, comprehensive reference volume. He highlights significant achievements in the area, and points to research directions and open problems. The book will be of interest to researchers and graduate students in theoretical computer science and mathematics, in particular those working in algebraic combinatorics and combinatorics on words. It will also be of interest to specialists in other branches of mathematics, theoretical physics, and computational biology.
