Download or read book Function and Evolution of Repeated DNA Sequences written by Guy-Franck Richard and published by John Wiley & Sons. This book was released on 2023-12-27 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genome of a living being is composed of DNA sequences with diverse origins. Beyond single-copy genes, whose product has a biological function that can be inferred by experimentation, certain DNA sequences, present in a large number of copies, escape the most refined approaches aimed at elucidating their precise role. The existence of what 20th century geneticists had already perceived (and wrongly described as "junk DNA"!) was confirmed by the sequencing of the first complex genomes, including that of Homo sapiens. A large part of what defines a living thing is not unique, but repeated, sometimes a very large number of times, increasing in complexity with successive duplications and multiplication. Understanding and defining the many functions of this myriad of repeated sequences, as well as their evolution through natural selection, has become one of the major challenges for 21st century genomics.

Download or read book Tandem Repeats in Genes Proteins and Disease written by Danny M. Hatters and published by Humana. This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genomes of humans, as well as many other species, are interspersed with hundreds of thousands of tandem repeats of DNA sequences. Those tandem repeats located as codons within open reading frames encode amino acid runs, such as polyglutamine and polyalanine. Tandem repeats have not only been implicated in biological evolution, development and function but also in a large collection of human disorders. In Tandem Repeats in Genes, Proteins, and Disease: Methods and Protocols, expert researchers in the field detail many methods covering the analysis of tandem repeats in DNA, RNA and protein, in healthy and diseased states. This will include molecular genetics, molecular biology, biochemistry, proteomics, biophysics, cell biology, and molecular and cellular approaches to animal models of tandem repeat disorders. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoratative and Practical, Tandem Repeats in Genes, Proteins, and Disease: Methods and Protocols aids scientists in continuing to study the unique methodological challenges that come from repetitive DNA and poly-amino acid sequences.

Download or read book Repetitive DNA Sequences written by Andrew G. Clark and published by MDPI. This book was released on 2020-03-05 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Repetitive DNA is ubiquitous in eukaryotic genomes, and, in many species, comprises the bulk of the genome. Repeats include transposable elements that can self-mobilize and disperse around the genome, and tandemly-repeated satellite DNAs that increase in copy number due to replication slippage and unequal crossing over. Despite their abundance, repetitive DNA is often ignored in genomic studies due to technical challenges in their identification, assembly, and quantification. New technologies and methods are now providing the unprecedented power to analyze repetitive DNAs across diverse taxa. Repetitive DNA is of particular interest because it can represent distinct modes of genome evolution. Some repetitive DNA forms essential genome structures, such as telomeres and centromeres, which are required for proper chromosome maintenance and segregation, whereas others form piRNA clusters that regulate transposable elements; thus, these elements are expected to evolve under purifying selection. In contrast, other repeats evolve selfishly and produce genetic conflicts with their host species that drive adaptive evolution of host defense systems. However, the majority of repeats likely accumulate in eukaryotes in the absence of selection due to mechanisms of transposition and unequal crossing over. Even these neutral repeats may indirectly influence genome evolution as they reach high abundance. In this Special Issue, the contributing authors explore these questions from a range of perspectives.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the role of tandem repeat polymorphisms (TRPs) in genetic plasticity, evolution, development, biological processes, neural diversity, brain function, dysfunction and disease. There are hundreds of thousands of unique tandem repeats in the human genome and their polymorphic distributions have the potential to greatly influence functional diversity and disease susceptibility. Recent discoveries in this expanding field are critically reviewed and discussed in a range of subsequent chapters, with a focus on the role of TRPs and their various gene products in evolution, development, diverse molecular and cellular processes, brain function and disease.

Download or read book Sequence Evolution Function written by Eugene V. Koonin and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequence - Evolution - Function is an introduction to the computational approaches that play a critical role in the emerging new branch of biology known as functional genomics. The book provides the reader with an understanding of the principles and approaches of functional genomics and of the potential and limitations of computational and experimental approaches to genome analysis. Sequence - Evolution - Function should help bridge the "digital divide" between biologists and computer scientists, allowing biologists to better grasp the peculiarities of the emerging field of Genome Biology and to learn how to benefit from the enormous amount of sequence data available in the public databases. The book is non-technical with respect to the computer methods for genome analysis and discusses these methods from the user's viewpoint, without addressing mathematical and algorithmic details. Prior practical familiarity with the basic methods for sequence analysis is a major advantage, but a reader without such experience will be able to use the book as an introduction to these methods. This book is perfect for introductory level courses in computational methods for comparative and functional genomics.
Download or read book Biological Sequence Analysis written by Richard Durbin and published by Cambridge University Press. This book was released on 1998-04-23 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Probabilistic models are becoming increasingly important in analysing the huge amount of data being produced by large-scale DNA-sequencing efforts such as the Human Genome Project. For example, hidden Markov models are used for analysing biological sequences, linguistic-grammar-based probabilistic models for identifying RNA secondary structure, and probabilistic evolutionary models for inferring phylogenies of sequences from different organisms. This book gives a unified, up-to-date and self-contained account, with a Bayesian slant, of such methods, and more generally to probabilistic methods of sequence analysis. Written by an interdisciplinary team of authors, it aims to be accessible to molecular biologists, computer scientists, and mathematicians with no formal knowledge of the other fields, and at the same time present the state-of-the-art in this new and highly important field.

Available in PDF, EPUB and Kindle. Book excerpt: This book gives a comprehensive overview of the unique roles that non-coding repetitive elements such as satellite DNAs play in different physiological and evolutionary processes. It presents the gene-regulatory aspect of satellite DNAs in different model systems including mammals, insects and plants. In addition, evolutionary aspects of activation of satellite DNAs in terms of transcription and proliferation are highlighted, revealing the role of satellite DNAs in the process of adaptation to changing environment and in the speciation process. Finally, the book discusses satellite DNA activation during pathological transformation and the mechanisms by which they affect disease progression. Namely, some satellite DNAs promote the oncogenic processes by affecting genome epigenetic regulation as well as genome integrity. Readers get a full overview of the latest research on satellite DNA.
