Unusual DNA Structures


Book Description

This book contains the papers which were presented at the First Gulf Shores Symposium on Unusual DNA Structures. The meeting was held April 6-8, 1987, in Gulf Shores, Alabama. Averitable explosion has taken place in recent years regarding our understanding of unusual DNA structures. This symposium was dedicated to enhancing our understanding of the biology and chemistry of these important structural features. The symposium was supported by funds provided by the Department of Biochemistry, University of Alabama at Birmingham, Schools of Medicine and Dentistry. We wish to express our app~eciationto Ms. Patti Guyton for her expert organizational skills and assistance in organizing the meeting and preparation of this book. Robert D. Wells and Stephen C.

DNA in Supramolecular Chemistry and Nanotechnology


Book Description

This book covers the emerging topic of DNA nanotechnology and DNA supramolecular chemistry in its broader sense. By taking DNA out of its biological role, this biomolecule has become a very versatile building block in materials chemistry, supramolecular chemistry and bio-nanotechnology. Many novel structures have been realized in the past decade, which are now being used to create molecular machines, drug delivery systems, diagnosis platforms or potential electronic devices. The book combines many aspects of DNA nanotechnology, including formation of functional structures based on covalent and non-covalent systems, DNA origami, DNA based switches, DNA machines, and alternative structures and templates. This broad coverage is very appealing since it combines both the synthesis of modified DNA as well as designer concepts to successfully plan and make DNA nanostructures. Contributing authors have provided first a general introduction for the non-specialist reader, followed by a more in-depth analysis and presentation of their topic. In this way the book is attractive and useful for both the non-specialist who would like to have an overview of the topic, as well as the specialist reader who requires more information and inspiration to foster their own research.




Structural DNA Nanotechnology


Book Description

Written by the founder of the field, this is a comprehensive and accessible introduction to structural DNA nanotechnology.




DNA Structure and Function


Book Description

DNA Structure and Function, a timely and comprehensive resource, is intended for any student or scientist interested in DNA structure and its biological implications. The book provides a simple yet comprehensive introduction to nearly all aspects of DNA structure. It also explains current ideas on the biological significance of classic and alternative DNA conformations. Suitable for graduate courses on DNA structure and nucleic acids, the text is also excellent supplemental reading for courses in general biochemistry, molecular biology, and genetics. - Explains basic DNA Structure and function clearly and simply - Contains up-to-date coverage of cruciforms, Z-DNA, triplex DNA, and other DNA conformations - Discusses DNA-protein interactions, chromosomal organization, and biological implications of structure - Highlights key experiments and ideas within boxed sections - Illustrated with 150 diagrams and figures that convey structural and experimental concepts




Principles of Nucleic Acid Structure


Book Description

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.




Structural Biology and Functional Genomics


Book Description

Biomedical research will be revolutionised by the current efforts to sequence the human genome and the genomes of model organisms. Of the newly sequenced genes, 50% code for proteins of unknown functions, while as little as 5% of sequences in mammalian genomes code for proteins. New, genome-wide approaches are needed to draw together the knowledge that is emerging simultaneously in a number of fields of genome research. This volume is a high-level survey of the newly emerging concepts of structural biology and functional genomics for biologists, biochemists and medical researchers interested in genome research. Topics included are chromosome and chromatin organisation, novel DNA and RNA structures, DNA flexibility, supercoiling, prediction of protein functions, strategies for large scale structural analysis, and computer modelling.




Topology and Physics of Circular DNA (1992)


Book Description

Topology and Physics of Circular DNA presents comprehensive coverage of the physical properties of circular DNA. The author examines how topological constraints arising from cyclization of DNA lead to distinctive properties that make closed molecules radically different from linear DNA. The phenomenon of supercoiling, its geometric and topological analysis, and the formation of noncanonical structures in circular DNA under the influence of supercoiling are emphasized. The combination of consistent theoretical analysis and detailed treatment of major experimental approaches make Topology and Physics of Circular DNA an important reference volume for biophysicists, biochemists, molecular biologists, and researchers and students who want to expand their understanding of circular DNA.




Mapping and Sequencing the Human Genome


Book Description

There is growing enthusiasm in the scientific community about the prospect of mapping and sequencing the human genome, a monumental project that will have far-reaching consequences for medicine, biology, technology, and other fields. But how will such an effort be organized and funded? How will we develop the new technologies that are needed? What new legal, social, and ethical questions will be raised? Mapping and Sequencing the Human Genome is a blueprint for this proposed project. The authors offer a highly readable explanation of the technical aspects of genetic mapping and sequencing, and they recommend specific interim and long-range research goals, organizational strategies, and funding levels. They also outline some of the legal and social questions that might arise and urge their early consideration by policymakers.




Triple-Helical Nucleic Acids


Book Description

The ability of DNA to exist in configurations other than its classical double-stranded form has been known for many years. There has been a spectacular recent surge of interest in these forms, notably in the three-stranded or triple-helical form. Triplex-like nucleic acids are now known to exist in vivo, and may well participate in significant biological processes. Interest in triple-helical nucleic acids has been greatly stimulated by their potential exploitation to control gene expression, serve as tools in genome mapping strategies, etc. The authors have written an encyclopedic introduction to nucleic acid triplexes based on many years of familiarity with the topic. The book includes information on chemistry, conformation, physical properties, applications, and hypotheses about the biological role of triplexes. It pays particular attention to the different methods for investigating these molecules, a feature which will be welcomed by those new to the field.
