Molecular Biology is a rapidly advancing field with a constant flow of new information and cutting-edge developements that impact our lives. Lewin's GENES has long been the essential resource for providing the teaching community with the most modern presentation to this dynamic area of study. GENES XI continues this tradition by introducing the most current data from the field, covering gene structure, sequencing, organization, and expression. It has enlisted a wealth of subject-matter experts, from top institutions, to provide content updates and revisions in their individual areas of study. A reorganized chapter presentation provides a clear, more student-friendly introduction to course material than ever before. - Updated content throughout to keep pace with this fast-paced field.- Reorganized chapter presentation provides a clear, student-friendly introduction to course material.- Expanded coverage describing the connection between replication and the cell cycle is included, and presents eukaryotes as well as prokaryotes.- Available with new online Molecular Biology Animations.- Online access code for the companion website is included with every new book. The companion website offers numerous study aids and learning tools to help students get the most out of their course.- Instructor's supplements include: PowerPoint Image Bank, PowerPoint Lecture Slides, and Test Bank.

A flawless flow of gold shine, the Eycee Ear Cuff features a subtle dome hump along the apex of its concave design. A perfect minimal addition to everyday earssentials. Style Tips: The Eycee Ear Cuff is best styled with the Viea classics, either the Gene Earrings or the Arabella Earrings, for that classy glimmer of gold. JEWELRY MATERIAL High quality 18k Gold Coated Stainless Steel Hypoallergenic, Waterproof & Non-tarnish VIEA pieces are treated with an anti-tarnish coating to help protect against tarnishing and scratches, yet it is still important for you to follow our care instructions to maintain and preserve the shine. SHINE PRESERVATION We recommend that the jewelry be removed before going to bed or participating in extreme physical activities. Exposure to certain harsh chemicals or environments will result in compromising the radiance of your jewelry. This includes, but is not limited to the following: perspiration, perfumes, cleaning agents, chlorine, salt water, and silver polish. CLEANING Using a small, slightly damp, soft cloth lightly polish your jewelry until the shine has visibly improved. If the dirt is hard to remove, soak the jewelry in clean water. STORAGE Store your jewelry in our signature Viea pouch, away from humid places, direct sunlight and heat. NOTE Gold plated and Gold Vermeil pieces are, by default, more fragile and liable to lose their colour over time. However, Viea pieces can last for a long time, years at that, once specially cared for. For this reason, it is particularly important to take special care of your jewelry to ensure a quality that lasts.

This volume builds upon the work of its predecessor in the third series of the Atlas of Tumor Pathology, liberally illustrating the spectrum of each tumor and disease described, while providing many new illustrations. Morphometry, flow cytometry, immunohistochemistry, gene rearrangement studies, and other molecular biologic methodologies are exciting new areas that are being developed into diagnostic procedures in the pathology laboratory. Where these methodologies are applicable to salivary gland disease, they are included. Histomorphologic evaluation, however, remains the principal and most useful method for diagnosis of salivary gland tumors and is the emphasis of this Fascicle. A differential diagnosis is included in the discussion of most tumors, and the cytopathologic features of those tumors most commonly encountered in the cytopathology laboratory are discussed.

The study of patterns and processes of evolution on islands has played an important role in the development of general theories of how and why evolution occurs. Isolated from the continental process of gene flow, islands may display remarkable rapidity of diversifying evolution, as well as unique species. Evolution on Islands surveys our current knowledge and understanding of microevolution, speciation, and adaptive radiation on islands. Chapters written by experts in the field cover the major trends and processes displayed by plants and animals, on tropical and temperate zone islands, and in lakes and tropical forest refugia. This groundbreaking volume will be of interest to all students and researchers working in the fields of ecology and evolutionary biology.

According to polling data, most Americans doubt that evolution is a real phenomenon. And it’s no wonder that so many are skeptical: many of today’s biology courses and textbooks dwell on the mechanisms of evolution—natural selection, genetic drift, and gene flow—but say little about the evidence that evolution happens at all. How do we know that species change? Has there really been enough time for evolution to operate? With The Evidence for Evolution, Alan R. Rogers provides an elegant, straightforward text that details the evidence for evolution. Rogers covers different levels of evolution, from within-species changes, which are much less challenging to see and believe, to much larger ones, say, from fish to amphibian, or from land mammal to whale. For each case, he supplies numerous lines of evidence to illustrate the changes, including fossils, DNA, and radioactive isotopes. His comprehensive treatment stresses recent advances in knowledge but also recounts the give and take between skeptical scientists who first asked “how can we be sure” and then marshaled scientific evidence to attain certainty. The Evidence for Evolution is a valuable addition to the literature on evolution and will be essential to introductory courses in the life sciences.

The origin of biological diversity, via the formation of new species, can be inextricably linked to adaptation to the ecological environment. Specifically, ecological processes are central to the formation of new species when barriers to gene flow (reproductive isolation) evolve between populations as a result of ecologically-based divergent natural selection. This process of 'ecological speciation' has seen a large body of particularly focused research in the last 10-15 years, and a review and synthesis of the theoretical and empirical literature is now timely.The book begins by clarifying what ecological speciation is, its alternatives, and the predictions that can be used to test for it. It then reviews the three components of ecological speciation and discusses the geography and genomic basis of the process. A final chapter highlights future research directions, describing the approaches and experiments which might be used to conduct that future work. The ecological and genetic literature is integrated throughout the text with the goal of shedding new insight into the speciation process, particularly when the empirical data is then further integrated with theory.
