The Recombination of Genetic Material aims to introduce the elementary properties of recombinational phenomena. Genetic recombination is a favorite research topic in biology due to its significance. In fact, a simple recombination event can have a profound effect and sometimes can mean the difference between the survival and the demise of an organism. Examples of this are provided in this book. This work also describes numerous recombination systems, mechanisms of the major types of recombination, and the macroscopic products of this biological process. Molecular analyses of recombination enzymes and substrates that have been identified or implicated are also shown. This book will be valuable as a reference material to those interested in this field of study.

"As the amount of information in biology expands dramatically, it becomes increasingly important for textbooks to distill the vast amount of scientific knowledge into concise principles and enduring concepts. As with previous editions, Molecular Biology of the Cell, Sixth Edition accomplishes this goal with clear writing and beautiful illustrations. The Sixth Edition has been extensively revised and updated with the latest research in the field of cell biology, and it provides an exceptional framework for teaching and learning. The entire illustration program has been greatly enhanced. Protein structures better illustrate structure-function relationships, icons are simpler and more consistent within and between chapters, and micrographs have been refreshed and updated with newer, clearer, or better images. As a new feature, each chapter now contains intriguing open-ended questions highlighting "What We Don't Know," introducing students to challenging areas of future research. Updated end-of-chapter problems reflect new research discussed in the text. Thought-provoking end-of-chapter questions have been expanded to all chapters, including questions on developmental biology, tissues and stem cells, the immune system, and pathogens"--Provided by publisher.

The Reason for this Volume If we were to judge the seriousness of a psychosocial problem by the attention that the popular media give to it, we would have to conclude that the modem world is in the midst of an epidemic of pedophilic child sexual abuse. One can scarcely go more than a few weeks in any large metropolitan area without reading about one of the community's upstanding citizens discovered to have been sexually involved with children or adolescents. The attention that the popular media give this topic is paralleled by the attention that it receives in the social sciences, where literally dozens of books and more than a thousand articles have been published on it in the past few years. In fact, "child sexual abuse," along with "co-dependency" and "dysfunctional family," have become the avant-garde psychological cliches of the decade. However, most of the lay and professional literature, although voluminous, reflect a narrow anthropo-, ethno-, and chronocentrism that precludes any real understanding of the topic with anything more than the preconceptions of our times.

Many organisms share genetic material across species boundaries, sometimes with profound effects such as widespread antibiotic resistance among bacteria. This genetic sharing, known as horizontal gene transfer, has only recently been shown to occur in multicellular eukaryotes, and appears to be most prevalent among flowering plant mitochondrial genomes. My work has focused on two very different cases of mitochondrial horizontal gene transfer in an effort to better understand both the exceptions and the rules of gene transfer in plants. My first study details a transfer of a fragment of a mitochondrial gene, nad1, from a eudicot donor to an ancestor of the ginger family in monocots. While the genes involved in all but one of the known flowering plant transfers in the literature appear to be unused by the recipient, a portion of the foreign nad1 sequence in gingers appears to be functional. The transfer and its aftermath left signs of recombination between the native and foreign copies of the gene, perhaps enabling the foreign segment to supplant the native copy. My second study is an analysis of the complete mitochondrial genome sequence of Amborella trichopoda, which contains in excess of one hundred foreign mitochondrial genes, from multiple donors from multiple plant lineages: eudicots, mosses, and green algae. The lack of foreign genes from chloroplast genomes or from non-plant donors suggests a plant mitochondrial specific transfer mechanism such as mitochondrial fusion. To put the massive transfer of foreign DNA in Amborella in context, I conducted a third, exclusively bioinformatic, project studying the intracellular transfer of Amborella chloroplast DNA into the mitochondrial genome. The Amborella mitochondrial genome contains an order of magnitude more chloroplast-derived DNA than other sequenced mitochondrial genomes, and is also nearly an order of magnitude larger, suggesting that Amborella mitochondria may be more competent than other plant mitochondria and might therefore incorporate more exogenous DNA sequence.
