This book was released on 2012-12-06 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the primary structure of nucleic acids, i. e. , the determination of the nucleotide sequence in ribosomal, transfer, and messenger types of RNA and in DNA, is an essential preliminary to the attempt to correlate the structures of these compounds with their functions. This is one of the most urgent problems in molecular biology, for until it is solved it is im possible to understand fully the mechanisms of fundamental living processes. Research has naturally tended to concentrate on the nucleic acids of smallest molecular weight, namely the transfer RNAs, and tremendous progress has been made in recent years in the unraveling of their structure. In 1958-1959, when structural investigation was still in its infancy, it was even doubted whether the structure of any transfer RNA could be deter mined. No methods of isolating homogeneous preparations were available, and it was uncertain whether the very slight physical and chemical differences between tRNAs of different specificity would be sufficient to allow successful fractionation. When the first enriched preparations were obtained, there arose the problem of whether it was possible to determine the nucleotide sequence having regard to the limited number of heterogeneous structural elements present in tRNA. These doubts were resolved in 1965, when the structure of the first nucleic acid, alanine-specific transfer RNA, was unraveled in Holley's laboratory.
Download or read book The Aminoacyl tRNA Synthetases written by Michael Ibba and published by CRC Press. This book was released on 2005-04-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: By virtue of their role as catalysts of the aminoacylation reaction, the aminoacyl-tRNA synthetases ensure that the first step of translation is performed quickly and accurately. In this volume of 36 separate chapters, the many facets of this ancient and ubiquitous family are reviewed, including their surprising structural diversity, enzymology, tRNA interaction properties, and curious alternative functions. These chapters illustrate the degree to which the aminoacyl-tRNA synthetases employ a variety of mechanisms to carry out both the standard functions related to the synthesis of aminoacylated tRNA for protein synthesis, as well as the surprising functions associated with amino acid biosynthesis, cytokine function, and even the processivity of DNA replication. Other chapters explore the regulation of their synthesis, their role in disease, and their prospects as targets for antibacterial therapeutics. This monograph will be a valuable resource for all scientists interested in the fundamentals of protein synthesis from both a basic research and clinical perspective, as well as the relation of translational components to the evolution of the genetic code.

Download or read book Pre mRNA Processing written by Angus I. Lamond and published by Springer. This book was released on 2014-08-23 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: he past fifteen years have seen tremendous growth in our understanding of T the many post-transcriptional processing steps involved in producing func tional eukaryotic mRNA from primary gene transcripts (pre-mRNA). New processing reactions, such as splicing and RNA editing, have been discovered and detailed biochemical and genetic studies continue to yield important new insights into the reaction mechanisms and molecular interactions involved. It is now apparent that regulation of RNA processing plays a significant role in the control of gene expression and development. An increased understanding of RNA processing mechanisms has also proved to be of considerable clinical importance in the pathology of inherited disease and viral infection. This volume seeks to review the rapid progress being made in the study of how mRNA precursors are processed into mRNA and to convey the broad scope of the RNA field and its relevance to other areas of cell biology and medicine. Since one of the major themes of RNA processing is the recognition of specific RNA sequences and structures by protein factors, we begin with reviews of RNA-protein interactions. In chapter 1 David Lilley presents an overview of RNA structure and illustrates how the structural features of RNA molecules are exploited for specific recognition by protein, while in chapter 2 Maurice Swanson discusses the structure and function of the large family of hnRNP proteins that bind to pre-mRNA. The next four chapters focus on pre-mRNA splicing.

Download or read book Tempo and Mode in Evolution written by for the National Academy of Sciences and published by National Academies Press. This book was released on 1995-02-09 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since George Gaylord Simpson published Tempo and Mode in Evolution in 1944, discoveries in paleontology and genetics have abounded. This volume brings together the findings and insights of today's leading experts in the study of evolution, including Ayala, W. Ford Doolittle, and Stephen Jay Gould. The volume examines early cellular evolution, explores changes in the tempo of evolution between the Precambrian and Phanerozoic periods, and reconstructs the Cambrian evolutionary burst. Long-neglected despite Darwin's interest in it, species extinction is discussed in detail. Although the absence of data kept Simpson from exploring human evolution in his book, the current volume covers morphological and genetic changes in human populations, contradicting the popular claim that all modern humans descend from a single woman. This book discusses the role of molecular clocks, the results of evolution in 12 populations of Escherichia coli propagated for 10,000 generations, a physical map of Drosophila chromosomes, and evidence for "hitchhiking" by mutations.

Download or read book Modified Nucleic Acids in Biology and Medicine written by Stefan Jurga and published by Springer. This book was released on 2016-07-29 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is comprised of 18 chapters, covering various aspects of DNA modification and RNA modified bases. It also discusses in detail circular RNA, therapeutic oligonucleotides and their different properties. The chemical nature of DNA, RNA, protein and lipids makes these macromolecules easily modifiable, but they are also susceptible to damage from both endogenous and exogenous agents. Alkylation and oxidation show a potential to disrupt the cellular redox equilibrium and cause cellular damage leading to inflammation and even chronic disease. Furthermore, DNA damage can drive mutagenesis and the resulting DNA sequence changes can induce carcinogenesis and cancer progression. Modified nucleosides can occur as a result of oxidative DNA damage and RNA turnover, and are used as markers for various diseases. To function properly some RNA needs to be chemically modified post-transcriptionally. Dysregulation of the RNA-modification pattern or of the levels of the enzymes that catalyze these modifications alters RNA functionality and can result in complex phenotypes, likely due to defects in protein translation. While modifications are best characterized in noncoding ribonucleic acids like tRNA and rRNA, coding mRNAs have also been found to contain modified nucleosides. This book is a valuable resource, not only for graduate students but also researchers in the fields of molecular medicine and molecular biology.
Download or read book RNA 3D Structure Analysis and Prediction written by Neocles Leontis and published by Springer Science & Business Media. This book was released on 2012-06-05 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the dramatic increase in RNA 3D structure determination in recent years, we now know that RNA molecules are highly structured. Moreover, knowledge of RNA 3D structures has proven crucial for understanding in atomic detail how they carry out their biological functions. Because of the huge number of potentially important RNA molecules in biology, many more than can be studied experimentally, we need theoretical approaches for predicting 3D structures on the basis of sequences alone. This volume provides a comprehensive overview of current progress in the field by leading practitioners employing a variety of methods to model RNA 3D structures by homology, by fragment assembly, and by de novo energy and knowledge-based approaches.
