This work describes the current knowledge of biochemical mechanisms regulating initiation of DNA replication in Escherichia coli, which focuses on the control of activity of the DnaA protein. Examples of direct linkages between DNA replication and other cellular processes are provided. In addition, similarities of the mechanisms of regulation of DNA replication operating in prokaryotic and eukaryotic cells are identified, and implications for understanding more complex processes, like carcinogenesis are suggested.Studies of recent years provided evidence that regulation of DNA replication in bacteria is more complex than previously anticipated. Multiple layers of control seem to ensure coordination of this process with the increase of cellular mass and the division cycle. Metabolic processes and membrane composition may serve as points where integration of genome replication with growth conditions occurs. It is also likely that coupling of DNA synthesis with cellular metabolism may involve interactions of replication proteins with other macromolecular complexes, responsible for various cellular processes. Thus, the exact set of factors participating in triggering the replication initiation may differ depending on growth conditions. Therefore, understanding the regulation of DNA duplication requires placing this process in the context of the current knowledge on bacterial metabolism, as well as cellular and chromosomal structure. Moreover, in both Escherichia coli and eukaryotic cells, replication initiator proteins were shown to play other roles in addition to driving the assembly of replication complexes, which constitutes another, yet not sufficiently understood, layer of coordinating DNA replication with the cell cycle.
"What underlying forces are responsible for the observed patterns of variability, given a collection of DNA sequences?" In approaching this question a number of probability models are introduced and anyalyzed.Throughout the book, the theory is developed in close connection with data from more than 60 experimental studies that illustrate the use of these results.
This book provides an evolutionary conceptual framework for comparative genomics, with the ultimate objective of understanding the loss and gain of genes during evolution, the interactions among gene products, and the relationship between genotype, phenotype and the environment. The many examples in the book have been carefully chosen from primary research literature based on two criteria: their biological insight and their pedagogical merit. The phylogeny-based comparative methods, involving both continuous and discrete variables, often represent a stumbling block for many students entering the field of comparative genomics. They are numerically illustrated and explained in great detail. The book is intended for researchers new to the field, i.e., advanced undergraduate students, postgraduates and postdoctoral fellows, although professional researchers who are not in the area of comparative genomics will also find the book informative.
Massive data acquisition technologies, such as genome sequencing, high-throughput drug screening, and DNA arrays are in the process of revolutionizing biology and medicine. Using the mRNA of a given cell, at a given time, under a given set of conditions, DNA microarrays can provide a snapshot of the level of expression of all the genes in the cell. Such snapshots can be used to study fundamental biological phenomena such as development or evolution, to determine the function of new genes, to infer the role individual genes or groups of genes may play in diseases, and to monitor the effect of drugs and other compounds on gene expression. Originally published in 2002, this inter-disciplinary introduction to DNA arrays will be of value to anyone with an a interest in this powerful technology.
Through the use of dramatic narratives, The Drama of DNA brings to
life the complexities raised by the application of genomic
technologies to health care and diagnosis. This creative,
pedagogical approach shines a unique light on the ethical,
psychosocial, and policy challenges that emerge as comprehensive
sequencing of the human genome transitions from research to
clinical medicine. Narrative genomics aims to enhance understanding
of how we evaluate, process, and share genomic information, and to
cultivate a deeper appreciation for difficult decisions encountered
by health care professionals, bioethicists, families, and society
as this technology reaches the bedside.
Darwin's The Origin of Species is one of the most influential books ever written. It is essential reading for anyone interested in biology, evolution, the natural world, or the history of scientific thought. However, the book can be difficult to follow. The sentences and paragraphs are lengthy, and Darwin often references people and ideas unfamiliar to contemporary readers. The Readable Darwin translates the sixth and final edition of Darwin's The Origin of Species (1872) into clear, engaging prose. Whereas the first edition of The Readable Darwin includes the first eight chapters of Darwin's book, this new edition presents all fifteen chapters of The Origin of Species and features over 100 illustrations. The Readable Darwin begins by discussing artificial selection, demonstrating that selection for new traits can indeed be made to occur, even within our lifetimes. It then presents evidence for natural selection derived from developmental traits and the geological record. Throughout, Pechenik painstakingly revises Darwin's prose. He breaks up long paragraphs, shortens and reorganizes sentences, and replaces weak verbs with strong ones. Footnotes clarify concepts, define terms, and identify the many historical figures Darwin mentions. The Origin of Species is a foundational work of scholarship in the biological sciences. It documents the remarkable diversity of life on earth and is a wonderful example of honest and logical scientific thinking. The Readable Darwin brings this groundbreaking book to life for readers of all backgrounds while remaining true to the original text.
Designed as an introductory text the authors cover all core strategies in the application of modern recombinant DNA technology. The first chapters directly address the applications of polymerase chain reaction to a variety of problems in DNA cloning that are, or have been, extremely challenging using more traditional approaches and technologies. These include cDNA cloning and transcript mapping, mutagenesis as well as the cloning of very long transcripts and protocols using limiting amounts of total RNA. Further chapters describe approaches to subtractive cloning technologies as well as novel specialized expression cloning and library screening strategies. The handbook contains detailed step-by-step protocols and extensive hands-on advice.
Internationally acclaimed science writer Lone Frank swabs up her DNA to provide the first truly intimate account of the new science of consumer-led genomics. She challenges the business mavericks intent on mapping every baby's genome, ponders the consequences of biological fortune-telling, and prods the psychologists who hope to uncover just how much or how little our environment will matter in the new genetic century - a quest made all the more gripping as Frank considers her family's and her own struggles with depression.

Transcription factors are the molecules that the cell uses to interpret the genome: they possess sequence-specific DNA-binding activity, and either directly or indirectly influence the transcription of genes. In aggregate, transcription factors control gene expression and genome organization, and play a pivotal role in many aspects of physiology and evolution. This book provides a reference for major aspects of transcription factor function, encompassing a general catalogue of known transcription factor classes, origins and evolution of specific transcription factor types, methods for studying transcription factor binding sites in vitro, in vivo, and in silico, and mechanisms of interaction with chromatin and RNA polymerase."
Adenine Nucleotides play a major role in cellular metabolism and functions, serving as high-potential phosphate transfer compounds in energy metabolism and as substrates and co-factors for proteins involved in signal transduction. During the last few years definite advancement has been made in elucidating the molecular and genetic aspects of the enzyme involved in oxidative phosphorylation, the so-called FoFl H~-ATP synthase. Non-invasive NMR technologies have been developed to monitor in vivo the energy level of tissues based on determination of the concentrations of adenine nucleotides, phosphate and phosphate esters. Thus it became clear that the capacity of oxidative phosphorylation adapts itself to the ATP demand which changes continuously with the physiological state in various tissues. This is achieved by regulation of the enzyme activity as well as by regulation of its biogenesis. The reversible phosphorylation of proteins is re- cognised as a major regulatory mechanism in eukaryotic as well as in prokaryotic cells for cellular signal transduction and control of gene expression, cell growth, differentation and oncogenesis. The same applies to the role played by cAMP. A further topic of growing interest concerns the discovery of the ATP binding cassette (ABC) superfamily of transport proteins which includes systems of primary importance in medicine such as the multi-drug resistance P glycoprotein, the cystic fibrosis transmembrane conductance regulator (CFTR) and the 70 kd peroxisomal membrane protein. Finally, much attention is being devoted in many laboratories to the molecular structure and role of ATP- modulated channels.
Winner of the 2014 Diamond Anniversary Book Award Finalist for the 2014 National Communications Association Critical and Cultural Studies Division Book of the Year Award In 2000, the National Human Genome Research Institute announced the completion of a "draft" of the human genome, the sequence information of nearly all 3 billion base pairs of DNA. Since then, interest in the hereditary basis of disease has increased considerably. In The Material Gene, Kelly E. Happe considers the broad implications of this development by treating "heredity" as both a scientific and political concept. Beginning with the argument that eugenics was an ideological project that recast the problems of industrialization as pathologies of gender, race, and class, the book traces the legacy of this ideology in contemporary practices of genomics. Delving into the discrete and often obscure epistemologies and discursive practices of genomic scientists, Happe maps the ways in which the hereditarian body, one that is also normatively gendered and racialized, is the new site whereby economic injustice, environmental pollution, racism, and sexism are implicitly reinterpreted as pathologies of genes and by extension, the bodies they inhabit. Comparing genomic approaches to medicine and public health with discourses of epidemiology, social movements, and humanistic theories of the body and society, The Material Gene reworks our common assumption of what might count as effective, just, and socially transformative notions of health and disease.
Depite the rapid expansion of the field of biophysics, there are very few books that comprehensively treat specific topics in this area. Recently, the field of single molecule biophysics has developed very quickly, and a few books specifically treating single molecule methods are beginning to appear. However, the promise of single molecule biophysics is to contribute to the understanding of specific fields of biology using new methods. This book would focus on the specific topic of the biophysics of DNA-protein interactions, and would include the use of new approaches, including both bulk methods as well as single molecule methods. This would make the book attractive to anyone working in the general area of DNA-protein interactions, which is of course a much wider market than just single molecule biophysicists or even biophysicists. The subject of the book will be the biophysics of DNA-protein interactions, and will include new methods and results that describe the physical mechanism by which proteins interact with DNA. For example, there has been much recent work on the mechanism by which proteins search for specific binding sites on DNA. A few chapters will be devoted to experiments and theory that shed light on this important problem. We will also cover proteins that alter DNA properties to facilitate interactions important for transcription or replication. Another section of the book will cover the biophysical mechanism by which motor proteins interact with DNA. Finally, we will cover larger protein-DNA complexes, such as replication forks, recombination complexes, DNA repair interactions, and their chromatin context.

Through many recent remarkable developments, perhaps the most significant advancements in the study of transcriptional regulation are the development of genome-wide approaches for measuring gene expression, exemplified by gene chips (chip), and chromatin immunoprecipitation assays (ChIP) for measuring "in vivo" protein-DNA interactions at any genomic loci. "Transcriptional Regulation: Methods and Protocols" takes this progress and builds upon it with a collection of key protocols used in expert laboratories around the world. Divided into four convenient sections, this detailed volume explores promoter elements, transcription factors, and preinitiation complex (PIC) assembly, chromatin structure, chromatin modifying complexes, and RNA synthesis and regulation. Written in the highly successful "Methods in Molecular Biology " series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and vital tips on troubleshooting and avoiding known pitfalls. Comprehensive and accessible, "Transcriptional Regulation: Methods and Protocols" equally serves senior researchers and scientists experienced in transcriptional regulation as well as graduate students and scientists who wish to study transcriptional regulation for the first time."
Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the twenty-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics. Nessa Carey, a leading epigenetics researcher, connects the field's arguments to such diverse phenomena as how ants and queen bees control their colonies; why tortoiseshell cats are always female; why some plants need cold weather before they can flower; and how our bodies age and develop disease. Reaching beyond biology, epigenetics now informs work on drug addiction, the long-term effects of famine, and the physical and psychological consequences of childhood trauma. Carey concludes with a discussion of the future directions for this research and its ability to improve human health and well-being.
This book is the first of its kind to provide a large collection of bioinformatics problems with accompanying solutions. Notably, the problem set includes all of the problems offered in Biological Sequence Analysis, by Durbin et al. (Cambridge, 1998), widely adopted as a required text for bioinformatics courses at leading universities worldwide. Although many of the problems included in Biological Sequence Analysis as exercises for its readers have been repeatedly used for homework and tests, no detailed solutions for the problems were available. Bioinformatics instructors had therefore frequently expressed a need for fully worked solutions and a larger set of problems for use on courses. This book provides just that: following the same structure as Biological Sequence Analysis and significantly extending the set of workable problems, it will facilitate a better understanding of the contents of the chapters in BSA and will help its readers develop problem-solving skills that are vitally important for conducting successful research in the growing field of bioinformatics. All of the material has been class-tested by the authors at Georgia Tech, where the first ever MSc degree program in Bioinformatics was held.
This book facilitates the introduction of SAGE into the laboratory and provides a framework for interpreting and comparing data derived from SAGE experiments. SAGE studies encompass 50,000 tags and can provide detailed knowledge of the 2000 most highly expressed genes in the tissue sample. The SAGE protocols presented are detailed, fully annotated, and tested, and are all written by experienced SAGE researchers from around the world.
Epigenetics refers to heritable patterns of gene expression which do not depend on alterations of genomic DNA sequence. This book provides a state-of-the-art account of a few selected hot spots by scientists at the edge in this extremely active field. It puts special emphasis on two main streams of research. One is the role of post-translational modifications of proteins, mostly histones, on chromatin structure and accessibility. The other one deals with parental genomic imprinting, a process which allows to express a few selected genes from only one of the parental allele while extinguishing the other.
