Available in PDF, EPUB and Kindle. Book excerpt: Mechanisms of Eukaryotic DNA Recombination is a collection of papers that discusses advances in eukaryotic genetic recombination. Papers address issues in eukaryotic genetic recombination, particularly DNA integration in mammalian genomes, genetic recombination in Drosophila or Caenorhabditis; the manipulation of the mouse genome; genome organization; and genetic recombination in protozoa. One paper discusses chromatid interactions during intrachromosomal recombination in mammalian cells, namely, intrachromatid and sister chromatid. Another paper analyzes the implication for chromosomal recombination and gene targeting; results on extrachromosomal recombination show that circles are inefficient substrates for recombination even if only one of two substrates in an intermolecular reaction is circular. One author discusses the genetics and molecular biology of recombination, citing the work of Watson and Crick, stating that crossing-over occurs between genes (not within them). He also explains that the formation and resolution of recombination intermediaries depend on enzyme or other proteins. This book will prove invaluable to cellular biologists, microbiologists, and researchers engaged in genetics and general biology.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the papers presented at the Twenty-Seventh Annual Biology Division Research Conference which was held April 1-4, 1974 in Gatlinburg, Tennessee. The topic of the symposium was Mechanisms in Recombination and it follows by exactly twenty years the previous Gatlinburg Symposium on Genetic Recombination. During this interval, and the preceding years as well, the process of recombination has remained a central and tantalizing problem for geneticists. The subject assumes added significance with the recent appeal by a committee of leading scientists for a moratorium on the construction of certain types of recombinant molecules. That autonomously replicating molecules linking portions of pro karyotic and eukaryotic DNA can now be produced in vitro attests to the technical advances that have taken place in this field. Nevertheless, the details underlying the process in vivo continue to be elusive. This symposium brought together individuals studying recombi nation in organisms as widely separated as bacteriophage and mammals and using disciplinary approaches of comparable diversity. Conse quently the present volume summarizes much of current strategies and concepts concerning the subject. The meeting was sponsored by the Biology Division of the Oak Ridge National Laboratory (operated by the Union Carbide Corporation for the U. S. Atomic Energy Commission) with the support and encour agement of its director, H. I. Adler. The organizing committee was chaired by J. K. Setlow and included R. F. Grell, R. D. Hotchkiss and E. Volkin. Special thanks are due to the speakers, to I. R.

Download or read book DNA Replication Recombination and Repair written by Fumio Hanaoka and published by Springer. This book was released on 2016-01-22 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive review of the detailed molecular mechanisms of and functional crosstalk among the replication, recombination, and repair of DNA (collectively called the "3Rs") and the related processes, with special consciousness of their biological and clinical consequences. The 3Rs are fundamental molecular mechanisms for organisms to maintain and sometimes intentionally alter genetic information. DNA replication, recombination, and repair, individually, have been important subjects of molecular biology since its emergence, but we have recently become aware that the 3Rs are actually much more intimately related to one another than we used to realize. Furthermore, the 3R research fields have been growing even more interdisciplinary, with better understanding of molecular mechanisms underlying other important processes, such as chromosome structures and functions, cell cycle and checkpoints, transcriptional and epigenetic regulation, and so on. This book comprises 7 parts and 21 chapters: Part 1 (Chapters 1–3), DNA Replication; Part 2 (Chapters 4–6), DNA Recombination; Part 3 (Chapters 7–9), DNA Repair; Part 4 (Chapters 10–13), Genome Instability and Mutagenesis; Part 5 (Chapters 14–15), Chromosome Dynamics and Functions; Part 6 (Chapters 16–18), Cell Cycle and Checkpoints; Part 7 (Chapters 19–21), Interplay with Transcription and Epigenetic Regulation. This volume should attract the great interest of graduate students, postdoctoral fellows, and senior scientists in broad research fields of basic molecular biology, not only the core 3Rs, but also the various related fields (chromosome, cell cycle, transcription, epigenetics, and similar areas). Additionally, researchers in neurological sciences, developmental biology, immunology, evolutionary biology, and many other fields will find this book valuable.

Download or read book Aspects of Eukaryotic DNA Replication Repair and Recombination written by Xin Chenglin Li and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanism that replicates, maintains, and sometimes alters the DNA is most fundamental and important for life. Three processes (DNA Replication, Repair, and Recombination) that are involved in this mechanism are closely related and well conserved in evolution. In my Ph.D. studies, I have used the cross model-organism approach to investigate the molecular mechanisms of DNA replication stress induced cancer as well as meiosis disruption caused infertility. Mcm4Chaos3, which encodes a mutant subunit of the hexameric MCM helicase, was previously reported to cause genetic instability (GIN) in mice and predispose homozygous female mice to mammary adenocarcinomas. My results show that homozygous diploid yeast carrying the equivalent mutation are defective in replicating long terminal repeat (LTR) elements. The replication stress at these interspersed repeat sequences coupled with error prone repair is the source of GIN, which is the driving force for the acquisition of an accelerated proliferation (AP) phenotype with aneuploidy as byproducts. I showed that mutations unrelated to aneuploidy are the cause of the AP phenotype. Moreover, the fragility of LTR regions is dependent on ploidy. The LTRs are not vulnerable to replication stress in haploid yeast and mcm4Chaos3 haploids use other repair pathways without generating GIN. Therefore, the dichotomy of consequences of DNA replication stress and repair pathway choice stems from cell-type specific regulation of fragile sites. In mammalian meiosis, homologous chromosome synapsis is coupled with recombination. As in most eukaryotes, mammalian meiocytes have checkpoints that monitor the fidelity of these processes. I reported that the mouse ortholog (Trip13) of pachytene checkpoint 2 (PCH2), an essential component of the synapsis checkpoint in S. cerevisiae and C. elegans, is required after strand invasion for completing a subset of recombination events, but possibly not those destined to be crossovers (Li and Schimenti 2007). TRIP13-deficient mice exhibit spermatocyte death in pachynema and loss of oocytes around birth. The chromosomes of mutant spermatocytes synapse fully, yet retain several markers of recombination intermediates. This is the first model to separate recombination defects from asynapsis in mammalian meiosis. Surprisingly, we found no evidence for checkpoint function, suggesting different pachytene checkpoint mechanisms may be involved in different species (Li et al. 2008).

Download or read book Concepts of Biology written by Samantha Fowler and published by . This book was released on 2018-01-07 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Initiation of DNA Replication in Eukaryotes written by Daniel L. Kaplan and published by Springer. This book was released on 2016-02-11 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: ​Every time a cell divides, a copy of its genomic DNA has to be faithfully copied to generate new genomic DNA for the daughter cells. The process of DNA replication needs to be precisely regulated to ensure that replication of the genome is complete and accurate, but that re-replication does not occur. Errors in DNA replication can lead to genome instability and cancer. The process of replication initiation is of paramount importance, because once the cell is committed to replicate DNA, it must finish this process. A great deal of progress has been made in understanding how DNA replication is initiated in eukaryotic cells in the past ten years, but this is the first one-source book on these findings. The Initiation of DNA Replication in Eukaryotes will focus on how DNA replication is initiated in eukaryotic cells. While the concept of replication initiation is simple, its elaborate regulation and integration with other cell processes results in a high level of complexity. This book will cover how the position of replication initiation is chosen, how replication initiation is integrated with the phases of the cell cycle, and how it is regulated in the case of damage to DNA. It is the cellular protein machinery that enables replication initiation to be activated and regulated. We now have an in-depth understanding of how cellular proteins work together to start DNA replication, and this new resource will reveal a mechanistic description of DNA replication initiation as well.

Download or read book Epigenetic Mechanisms of Gene Regulation written by Vincenzo E. A. Russo and published by . This book was released on 1996 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many inheritable changes in gene function are not explained by changes in the DNA sequence. Such epigenetic mechanisms are known to influence gene function in most complex organisms and include effects such as transposon function, chromosome imprinting, yeast mating type switching and telomeric silencing. In recent years, epigenetic effects have become a major focus of research activity. This monograph, edited by three well-known biologists from different specialties, is the first to review and synthesize what is known about these effects across all species, particularly from a molecular perspective, and will be of interest to everyone in the fields of molecular biology and genetics.
