The Double Strand

Two strands, one indigenous, the other imposed, pro-duce the poetic and cultural tensions that give form to the work of five contemporary Mexican poets -- All Chumacero, Efrain Huerta, Jaime Sabines, Ruben Bonifaz Nuno, and Rosario Castellanos. Although all five are significant figures, only Castellanos has yet been widely studied in the United States, primarily for her novels and her relations with the feminist movement. In spite of a number of rather basic differences in their work, these poets share and write within a complicated culture rooted in both the pre-Hispanic and the European traditions. Their poetry reflects this in its emphasis on death as a constant presence and in the echoes of both Aztec ritual poetry and European poetry. Although apparently very different formally and thematically, the five share a number of concerns. Each of them writes out of a contradictory inner tension; each is preoccupied with the effort to shape language as part of a personal voyage of discovery; each is haunted by death and seeks realization or plenitude through love of some kind. And each of them, ultimately, finds there is no escape. As Frank Dauster concludes, "The poetry of Mexico, like its people and its society, reflects the fusion of two worlds, and these complex poets of the double strand operate freely and imaginatively within it." Although addressed primarily to specialists in Latin American literature, The Double Strand also speaks to those interested in the complex interaction between two widely differing cultural heritages, and in the rich fusion this blending produces in Mexican letters.

Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

An essential resource for all scientists researching cellular responses to DNA damage. • Introduces important new material reflective of the major changes and developments that have occurred in the field over the last decade. • Discussed the field within a strong historical framework, and all aspects of biological responses to DNA damage are detailed. • Provides information on covering sources and consequences of DNA damage; correcting altered bases in DNA: DNA repair; DNA damage tolerance and mutagenesis; regulatory responses to DNA damage in eukaryotes; and disease states associated with defective biological responses to DNA damage.

Within the past two decades, extraordinary new functions for the nucleolus have begun to appear, giving the field a new vitality and generating renewed excitement and interest. These new discoveries include both newly-discovered functions and aspects of its conventional role. The Nucleolus is divided into three parts: nucleolar structure and organization, the role of the nucleolus in ribosome biogenesis, and novel functions of the nucleolus.

Since its publication in 1968, The Double Helix has given countless readers a rare and exciting look at one highly significant piece of scientific research-Watson and Crick's race to discover the molecular structure of DNA.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs. This is an adaptation of Microbiology by OpenStax. You can access the textbook as pdf for free at openstax.org. Minor editorial changes were made to ensure a better ebook reading experience.

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.

This volume discusses various aspects of mechanisms and methodologies of chromosome translocations, ranging from a historical and clinical overview of chromosome translocations to the rapid development of the next-generation sequencing technologies, which has dramatically increased our understanding of the spectrum of chromosome translocations in human diseases. The book also introduces the mechanistic studies on chromosome deletions and their implications in cancer, and discusses the mechanisms of regulating chromothripsis, a unique complex type of chromosome translocation. It is a valuable resource for students and researchers alike, providing insights into chromosome translocations and, potentially, other genomic aberrations involved in understanding and curing human diseases.
