With elegant simplicity, Maxim D. Frank-Kamenetskii elucidates the essential history and inner workings of DNA-a tiny molecule that holds within it the deepest mysteries of life. As Frank-Kamenetskii explains, DNA will undoubtedly shape our future, too, as we call upon it to convict criminals, clone creatures, and ultimately, cure cancer. This definitive guide to DNA, a previous version of which sold over 300,000 copies in the author's native Russia, promises to both inform and inspire.
Applied Antisense Oligonucleotide Technology
DNA ancestry companies generate revenues in the region of $1bn a year, and the company 23andMe is said to have sold 10 million DNA ancestry kits to date. Although evidently popular, the science behind how DNA ancestry tests work is mystifying and difficult for the general public to interpret and understand. In this accessible and engaging book, Sheldon Krimsky, a leading researcher, investigates the methods that different companies use for DNA ancestry testing. He also discusses what the tests are used for, from their application in criminal investigations to discovering missing relatives. With a lack of transparency from companies in sharing their data, absent validation of methods by independent scientists, and currently no agreed-upon standards of accuracy, this book also examines the ethical issues behind genetic genealogy testing, including concerns surrounding data privacy and security. It demystifies the art and science of DNA ancestry testing for the general reader.
What does it mean to say that mutation is random? How does mutation influence evolution? Are mutations merely the raw material for selection to shape adaptations? The author draws on a detailed knowledge of mutational mechanisms to argue that the randomness doctrine is best understood, not as a fact-based conclusion, but as the premise of a neo-Darwinian research program focused on selection. The successes of this research program created a blind spot - in mathematical models and verbal theories of causation - that has stymied efforts to re-think the role of variation. However, recent theoretical and empirical work shows that mutational biases can and do influence the course of evolution, including adaptive evolution, through a first come, first served mechanism. This thought-provoking book cuts through the conceptual tangle at the intersection of mutation, randomness, and evolution, offering a fresh, far-reaching, and testable view of the role of variation as a dispositional evolutionary factor. The arguments will be accessible to philosophers and historians with a serious interest in evolution, as well as to researchers and advanced students of evolution focused on molecules, microbes, evo-devo, and population genetics.
Barbara McClintock was born in 1902, within a few years of the rediscovery of Mendel's laws. Her life, discoveries, and insights span the history of genetics in this century. McClintock's unique ability to discern relationships between the behavior of chromosomes and the properties of the whole organism earned her early recognition. At Cold Spring Harbor, she began the studies of the consequence of dicentric chromosome formation and breakage that led her to the discovery of genetic elements capable of moving within the genome and controlling expression of other genes. This book contains a kaleidoscope of contributions, many by those who discovered transposition in other organisms. Their essays give a remarkable account of the scientific legacy of one of the century's greatest geneticists.
Candid, provocative, and disarming, this is the widely-praised memoir of the co-discoverer of the double helix of DNA.
Genome sequencing is one of the most exciting scientific breakthroughs of the past thirty years. But what precisely does it involve and how is it developing? In this brilliantly wide-ranging, one-stop guide WIRED journalist Rachael Pells explains the science behind genomics. She analyses its practical applications in medical diagnosis and the treatment of conditions that range from cancer to severe allergic reactions to cystic fibrosis. She considers its potential to help with advances in agriculture and environmental science. She explores the ethics of genetic modification and the dangers involved when humans 'play God'. And she addresses the fundamental question: to what extent will future advances transform human longevity and the quality of life.
Information is central to the evolution of biological complexity, a physical system relying on a continuous supply of energy. Biology provides superb examples of the consequent Darwinian selection of mechanisms for efficient energy utilisation. Genetic information, underpinned by the Watson-Crick base-pairing rules is largely encoded by DNA, a molecule uniquely adapted to its roles in information storage and utilisation.This volume addresses two fundamental questions. Firstly, what properties of the molecule have enabled it to become the predominant genetic material in the biological world today and secondly, to what extent have the informational properties of the molecule contributed to the expansion of biological diversity and the stability of ecosystems. The author argues that bringing these two seemingly unrelated topics together enables Schroedinger's What is Life?, published before the structure of DNA was known, to be revisited and his ideas examined in the context of our current biological understanding.
Fixing Your Damaged and Incorrect Genes is a book about a well-established biological process called DNA REPAIR. The book describes the multiple and varied biochemical strategies by which damaged or incorrect nucleotides are removed from DNA or are corrected. The book includes multiple figures of notable past and present scientists in the field. The book is uniquely focused on an audience of non-biologists and is written in simple language with minimal use of technical terms. It contains an extensive glossary that provides explanations of key words that readers are encouraged to refer to as they read. Fixing Your Damaged and Incorrect Genes is unique, there being no previously published books for non-biologists on the topic of DNA repair.
This book describes the driving forces behind the evolutionary process at the molecular and genome levels, the effects of the various molecular mechanisms on the structure of genes, proteins, and genomes, the methodology and the analytical tools involved in dealing with molecular data from an evolutionary perspective, and the logic of evolutionary hypothesis testing. Evolutionary phenomena at the molecular level are detailed in a way that can be understood without much prerequisite knowledge of molecular biology, evolution, or mathematics. Numerous examples that support and clarify the theoretical arguments and methodological discussions are included.
At least 5 trillion cell divisions are required for a fertilized egg to develop into an adult human, resulting in the production of more than 20 trillion meters of DNA! And yet, with only two exceptions, the genome is replicated once and only once each time a cell divides. How is this feat accomplished? What happens when errors occur? This book addresses these questions by presenting a thorough analysis of the molecular events that govern DNA replication in eukaryotic cells. The association between genome replication and cell proliferation, disease pathogenesis, and the development of targeted therapeutics is also addressed. At least 160 proteins are involved in replicating the human genome, and at least 40 diseases are caused by aberrant DNA replication, 35 by mutations in genes required for DNA replication or repair, 7 by mutations generated during mitochondrial DNA replication, and more than 40 by DNA viruses. Consequently, a growing number of therapeutic drugs are targeted to DNA replication proteins. This authoritative volume provides a rich source of information for researchers, physicians, and teachers, and will stimulate thinking about the relevance of DNA replication to human disease.
There have been remarkable advances towards discovering agents that exhibit selectivity and sequence-specificity for DNA, as well as understanding the interactions that underlie its propensity to bind molecules. This progress has important applications in many areas of biotechnology and medicine, notably in cancer treatment as well as in future gene targeting therapies. The editor and contributing authors are leaders in their fields and provide useful perspectives from diverse and interdisciplinary backgrounds on the current status of this broad area. The role played by chemistry is a unifying theme. Early chapters cover methodologies to evaluate DNA-interactive agents and then the book provides examples of DNA-interactive molecules and technologies in development as therapeutic agents. DNA-binding metal complexes, peptide and polyamide–DNA interactions, and gene targeting tools are some of the most compelling topics treated in depth. This book will be a valuable resource for postgraduate students and researchers in chemical biology, biochemistry, structural biology and medicinal fields. It will also be of interest to supramolecular chemists and biophysicists.
Fingerprints have provided a valuable method of personal identification in forensic science and criminal investigations for over 100 years. Fingerprints left at crime scenes generally are latent prints -- unintentional reproductions of the arrangement of ridges on the skin made by the transfer of materials (such as amino acids, proteins, polypeptides, and salts) to a surface. Palms and the soles of feet also have friction ridge skin that can leave latent prints. The examination of a latent print consists of a series of steps involving a comparison of the latent print to a known (or exemplar) print. Courts have accepted latent print evidence for the past century. However, several high-profile cases in the United States and abroad have highlighted the fact that human errors can occur, and litigation and expressions of concern over the evidentiary reliability of latent print examinations and other forensic identification procedures has increased in the last decade. This book discusses latent print examinations in detail, and provides methods to improving the practice through a systems approach.
The sequencing of the human genome was a pivotal event in science that opened the door to exploring the structure and function of genes and their regulation. The activation or suppression of transcribed genes is critical to the orchestration of everyday biological processes at the cellular, tissue, and physiological levels. The rapid advance of science and technology has yielded the development of the microarray technique, which has propelled a much deeper understanding of the genome. By combining these technological advances in microarrays with statistical and bioinformatics software, investigators are now able to perform scientific investigations geared towards answering unique biological problems that encompass many fields of research from genetics and evolution to molecular medicine, health, and disease. This book provides an overview of the use and application of microarrays throughout the life sciences to address diverse complex biological questions. In this collection, authors present information on using microarrays to unlock molecular mechanisms and gene expression patterns associated with research areas ranging from biodefense, pathological changes, and monitoring antimicrobial resistance genes to diagnostics, marine biodiversity, and dermal toxicology.
MicroRNAs are small non-coding RNAs involved in post-transcriptional regulation of gene expression. Thousands of miRNAs have been identified in different organisms including viruses, insects, plants and animals. MiRNAs has emerged as key regulators of important biological processes. The differential expression of miRNAs in various human diseases has made them potential candidates for developing novel therapies and personalized medicines. This book is focused on microRNA let-7, the second miRNA discovered in the year 2000 and one of the most studied miRNA. This book discusses various aspects of miRNA let-7 starting from its discovery, biogenesis, transcriptional and posttranscriptional regulation to its crucial role in various fundamental cellular processes such as development, stem cell maintenance and differentiation, regulation of signalling pathways in cancer, drug resistance and therapeutic potential in different human diseases.
Genome stability of every species depends on complex interaction of predefined and environmentally induced genetic and epigenetic states. Predefined states consist of chromatin structure and cell metabolic processes such as DNA repair, radical scavenging and cell signalling, whereas induced states depend on interactions with the environment. Organisms are able to respond to a changing environment by various alterations in their somatic cells as well as in their germline and progeny. In this book, we will describe various phenomena associated with the maintenance of genome stability. These include genetic and epigenetic responses to various stresses in exposed cells and organisms, bystander and, bystander-like effects, transgenerational changes in genome stability and stress tolerance in bacteria, plants and animals.
Polyhedra have attracted scientists' attentions due to their high-symmetric architectures since ancient times, and even served as common modes in natural world. Chemists in the past few centuries have strived to synthesise these polyhedral targets. Despite achievements that have been arrived, there is still a gap between the great varieties of polyhedral shapes observed in nature and the relatively limited molecular polyhedra constructed by small organic molecules. Fortunately, DNA was shown to be an excellent material in molecular construction. The construction of polyhedral structures with DNA improves the development of synthetic chemistry. This book reviews the recent progress made in the theoretical investigation of a new mathematical theory of DNA polyhedra.
Numerous physical and chemical stress factors, endogenous or exogenous, challenge living organisms. Metabolisation processes generate highly reactive intermediates which can covalently bind to DNA, resulting in bulky addition products called "adducts." DNA adduct formation appears to be a general response of plants to organic chemical exposure, whether in controlled conditions or in the field. In particular, common carcinogenic pollutants and pesticides promote the formation of DNA adducts in plants. The authors of this book examine the development of DNA adducts, as well as the ways in which they can be eliminated due to DNA repair pathways. In this book, the data from in vivo transgenic assays is also examined, which can help to clarify specific pre-mutagenic adducts, DNA repair functions and mutational events that may be involved in the mutagenicity of human carcinogens. Other chapters in this book identify and discuss novel anthracyclines capable of forming DNA adducts, the role of DNA adducts as early biomarkers in the screening and development of marine anticancer drugs, the genotoxicity, such as DNA adduct formation, of air pollutants and its assessment by in vivo mutagenesis and a discussion of oxidative DNA damage, which can play an important role in the carcinogenic processes of PAHs and aromatic amines, in addition to bulky-DNA adducts formation.

Quantitative traits-be they morphological or physiological characters, aspects of behavior, or genome-level features such as the amount of RNA or protein expression for a specific gene-usually show considerable variation within and among populations. Quantitative genetics, also referred to as the genetics of complex traits, is the study of such characters and is based on mathematical models of evolution in which many genes influence the trait and in which non-genetic factors may also be important. Evolution and Selection of Quantitative Traits presents a holistic treatment of the subject, showing the interplay between theory and data with extensive discussions on statistical issues relating to the estimation of the biologically relevant parameters for these models. Quantitative genetics is viewed as the bridge between complex mathematical models of trait evolution and real-world data, and the authors have clearly framed their treatment as such. This is the second volume in a planned trilogy that summarizes the modern field of quantitative genetics, informed by empirical observations from wide-ranging fields (agriculture, evolution, ecology, and human biology) as well as population genetics, statistical theory, mathematical modeling, genetics, and genomics. Whilst volume 1 (1998) dealt with the genetics of such traits, the main focus of volume 2 is on their evolution, with a special emphasis on detecting selection (ranging from the use of genomic and historical data through to ecological field data) and examining its consequences.
Over the last twenty years, genome-wide association studies (GWAS) have revealed a great deal about the genetic basis of a wide range of complex diseases and they will undoubtedly continue to have a broad impact as we move to an era of personalised medicine. This authoritative text, written by leaders and innovators from both academia and industry, covers the basic science as well as the clinical, biotechnological and pharmaceutical potential of these methods. With special emphasis given to highlighting pharmacogenomics and population genomics studies using next-generation technology approaches, this is the first book devoted to combining association studies with single nucleotide polymorphisms, copy number variants, haplotypes and expressed quantitative trait loci. A reliable guide for newcomers to the field as well as for experienced scientists, this is a unique resource for anyone interested in how the revolutionary power of genomics can be applied to solve problems in complex disease.
"We are sure that DNA: Forensic and Legal Applications will play
its part in promoting this most powerful tool in the forensic
scientist's armamentarium." Because it consists of a number of complex steps and procedures subject to both scientific and legal standards, the collection, analysis, presentation, and interpretation of DNA evidence remains a complex process. Any procedural or documentary misstep can potentially render key evidence or testimony useless. To avoid such costly errors, scientists, law enforcement personnel, attorneys, and judges all must possess a detailed knowledge of how forensic DNA works, from the crime scene to the laboratory to the courtroom and beyond. DNA: Forensic and Legal Applications provides the most comprehensive and up-to-date guide to this important and increasingly prevalent legal tool. Designed to reach readers in both legal and scientific fields, this text gives a global view of the practical issues involved in the forensic use of DNA. In clear, nontechnical language, the text covers:
In a unique combination of legal practice and scientific analysis, DNA: Forensic and Legal Applications provides forensic scientists, potential expert witnesses, and professionals in the criminal justice system with the definitive resource on the methods of DNA analysis as well as the handling, potential, and limitations of DNA evidence.
