Book excerpt: To understand the role of a charged nucleoside on charge transfer in DNA, we designed and synthesized cationic nucleoside mimics, which were incorporated into anthraquinone-linked DNA strands and irradiated at 350 nm. The presence of the cationic bases on the duplexes inhibits the migrating hole from hopping along the DNA strand, and induces a prominent local structural distortion of the DNA as a result of the charged nucleobase.

Book Synopsis Principles of Nucleic Acid Structure by : Wolfram Saenger
Download or read book Principles of Nucleic Acid Structure written by Wolfram Saenger and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: New textbooks at all levels of chemistry appear with great regularity. Some fields like basic biochemistry, organic reaction mechanisms, and chemical ther modynamics are well represented by many excellent texts, and new or revised editions are published sufficiently often to keep up with progress in research. However, some areas of chemistry, especially many of those taught at the grad uate level, suffer from a real lack of up-to-date textbooks. The most serious needs occur in fields that are rapidly changing. Textbooks in these subjects usually have to be written by scientists actually involved in the research which is advancing the field. It is not often easy to persuade such individuals to set time aside to help spread the knowledge they have accumulated. Our goal, in this series, is to pinpoint areas of chemistry where recent progress has outpaced what is covered in any available textbooks, and then seek out and persuade experts in these fields to produce relatively concise but instructive introductions to their fields. These should serve the needs of one semester or one quarter graduate courses in chemistry and biochemistry. In some cases the availability of texts in active research areas should help stimulate the creation of new courses. CHARLES R. CANTOR New York Preface This monograph is based on a review on polynucleotide structures written for a book series in 1976.

Book Synopsis Advances in DNA Sequence-Specific Agents by : J.B. Chaires
Download or read book Advances in DNA Sequence-Specific Agents written by J.B. Chaires and published by Elsevier. This book was released on 1996-07-09 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: DNA sequence specificity is a sub-specialty in the general area of molecular recognition. This area includes macromolecular-molecular interactions (e.g., protein-DNA), oligomer-DNA interacitons (e.g., triple strands), and ligand-DNA interactions (e.g., drug-DNA). It is this latter group of DNA sequence specificity interactions that is the subject of Volumes 1 and 2 of Advances in DNA Sequence Specific Agents. As was the case for Volume 1, Part A also covers methodology, but in Volume 2 we include calorimetric titrations, molecular modeling, X-ray crystallographic and NMR structural studies, and transcriptional assays. Part B also follows the same format as Volume 1 and describes the sequence specificities and covalent and noncovalent interactions of small ligands with DNA.This volume is aimed in general at scientists who have an interest in deciphering the molecular mechanisms for sequence recognition of DNA. The methods have general applicability to small molecules as well as oligomers and proteins, while the examples provide general principles involved in sequence recognition.

Book Synopsis Nucleic Acids by : Nancy C. Stellwagen
Download or read book Nucleic Acids written by Nancy C. Stellwagen and published by . This book was released on 2004 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Curvature and Deformation of Nucleic Acids: Recent Advances, New Paradigms presents an up-to-date review on the curvature and deformation of nucleic acids. Chapter 1 sets the various chapters in context, as well as describing several controversial topics. Chapter 2 gives a comprehensive review of the literature on DNA bending and describes the current status of molecular dynamics simulations of DNA and protein-DNA complexes. Chapter 3 describes the structural basis for A-tract DNA helix bending, based on recent NMR structures and other biophysical measurements. Chapter 4 describes the localization of Mg++ ions in the crystal structure of a B-form DNA dodecamer and discusses the relevance of these bound ions to sequence-dependent bending. Chapter 5 discusses the electrostatic energy penalties that result from phosphate crowding in curved DNA oligomers. Chapter 6 presents a quantitative model that predicts the magnitude of the bend caused by asymmetric charge neutralization of DNA phosphate residues. Chapter 7 reviews the structural and dynamic properties of four-way DNA junctions in the presence of metal ions, and it describes the exchange between alternative stacking conformers in solution. Chapter 8 documents the fact that a conserved pseudouridine residue in an RNA duplex containing a precursor messenger branch site makes an important contribution to the structure of the molecule. Chapter 9 describes structural perturbations that are observed in disease-related mutants of human mitochondrial transfer RNAs. Chapter 10 reviews the thermodynamics of the folding and unfolding of DNA oligomers distorted by the binding of small ligands. Chapter 11 describes a method of constructing DNA fragments for cyclization studies that uses single strand gaps as flexible hinges that allow the correct torsional orientation of the helix ends. Chapter 12 reviews a statistical mechanical model that predicts the stability of reconstituted nucleosomes based on sequence-dependent DNA curvature and flexibility.

Download or read book DNA written by James D. Watson and published by Knopf. This book was released on 2009-01-21 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifty years ago, James D. Watson, then just twentyfour, helped launch the greatest ongoing scientific quest of our time. Now, with unique authority and sweeping vision, he gives us the first full account of the genetic revolution—from Mendel’s garden to the double helix to the sequencing of the human genome and beyond. Watson’s lively, panoramic narrative begins with the fanciful speculations of the ancients as to why “like begets like” before skipping ahead to 1866, when an Austrian monk named Gregor Mendel first deduced the basic laws of inheritance. But genetics as we recognize it today—with its capacity, both thrilling and sobering, to manipulate the very essence of living things—came into being only with the rise of molecular investigations culminating in the breakthrough discovery of the structure of DNA, for which Watson shared a Nobel prize in 1962. In the DNA molecule’s graceful curves was the key to a whole new science. Having shown that the secret of life is chemical, modern genetics has set mankind off on a journey unimaginable just a few decades ago. Watson provides the general reader with clear explanations of molecular processes and emerging technologies. He shows us how DNA continues to alter our understanding of human origins, and of our identities as groups and as individuals. And with the insight of one who has remained close to every advance in research since the double helix, he reveals how genetics has unleashed a wealth of possibilities to alter the human condition—from genetically modified foods to genetically modified babies—and transformed itself from a domain of pure research into one of big business as well. It is a sometimes topsy-turvy world full of great minds and great egos, driven by ambitions to improve the human condition as well as to improve investment portfolios, a world vividly captured in these pages. Facing a future of choices and social and ethical implications of which we dare not remain uninformed, we could have no better guide than James Watson, who leads us with the same bravura storytelling that made The Double Helix one of the most successful books on science ever published. Infused with a scientist’s awe at nature’s marvels and a humanist’s profound sympathies, DNA is destined to become the classic telling of the defining scientific saga of our age.

Download or read book Health Risks from Exposure to Low Levels of Ionizing Radiation written by Committee to Assess Health Risks from Exposure to Low Levels of Ionizing Radiation and published by National Academies Press. This book was released on 2006-03-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the seventh in a series of titles from the National Research Council that addresses the effects of exposure to low dose LET (Linear Energy Transfer) ionizing radiation and human health. Updating information previously presented in the 1990 publication, Health Effects of Exposure to Low Levels of Ionizing Radiation: BEIR V, this book draws upon new data in both epidemiologic and experimental research. Ionizing radiation arises from both natural and man-made sources and at very high doses can produce damaging effects in human tissue that can be evident within days after exposure. However, it is the low-dose exposures that are the focus of this book. So-called “late” effects, such as cancer, are produced many years after the initial exposure. This book is among the first of its kind to include detailed risk estimates for cancer incidence in addition to cancer mortality. BEIR VII offers a full review of the available biological, biophysical, and epidemiological literature since the last BEIR report on the subject and develops the most up-to-date and comprehensive risk estimates for cancer and other health effects from exposure to low-level ionizing radiation.
