This book was released on 2012-12-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was at the end of the 19th century that a Swiss biologist, Karl Nageli first proposed the existence of hereditary organelles that carried information from parent to offspring. Ensuing decades experienced vigorous studies that led to the development of discovery that chromosomes are indeed the carriers of genetic information. Subsequent studies, especially by Morgan and Bridges, established unequivocally the chromosome theory of inheritance. Today, the structure of chromosome is well established. At the physical level, eukaryotic chromosomes are composed of a single, linear, double helix of DNA. The elementary helical structure involves nucleosomes, comprised of histones around which the DNA is wrapped. A hierarchy of higher order of chromosomal architecture may possibly be responsible for the regulation of gene helical structures expression. The localized condensations of DNA constitute chromomeres. Uncoiled structures sometimes extending from chromomeres, which form loops, is the result of discontinuities in the regular coiling of the DNA in the chromosome.

Available in PDF, EPUB and Kindle. Book excerpt: A Historical Perspective on the Study of Chromosome Structure and Function R. Appels Division of Plant Industry CSIRO P.O. Box 1600 A.C.T. AUSTRALIA "Modern physical science gives us no model to explain the re duplication of the gene-string in each cell generation, or to ex plain the production of effective quantities of specific enzymes or other agents by specific genes. The precise pairing and inter change of segments by homologous gene-strings at meiosis also suggest novel physical properties of this form of matter". Stadler (1954) The very strong influence of reductionism in the history of understanding chromosome structure and function is evident in the above quotation from Stadler's 1954 paper, "The gene". Earlyob servations on the constancy of the cytological appearance of chromo somes and their regular behaviour in cell division led to specula tion on their biological importance. As genetics became more refined in the early decades of the 20th century the genes-on-a string model of chromosomes developed and greater emphasis was placed on the further dissection of these structures. As a result, in the 1980's the reductionist approach is reaching a crest as extensive regions of the genetic material are being sequenced.
Download or read book Chromosomes written by Adrian T. Sumner and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrating classical knowledge of chromosome organisation with recent molecular and functional findings, this book presents an up-to-date view of chromosome organisation and function for advanced undergraduate students studying genetics. The organisation and behaviour of chromosomes is central to genetics and the equal segregation of genes and chromosomes into daughter cells at cell division is vital. This text aims to provide a clear and straightforward explanation of these complex processes. Following a brief historical introduction, the text covers the topics of cell cycle dynamics and DNA replication; mitosis and meiosis; the organisation of DNA into chromatin; the arrangement of chromosomes in interphase; euchromatin and heterochromatin; nucleolus organisers; centromeres and telomeres; lampbrush and polytene chromosomes; chromosomes and evolution; chromosomes and disease, and artificial chromosomes. Topics are illustrated with examples from a wide variety of organisms, including fungi, plants, invertebrates and vertebrates. This book will be valuable resource for plant, animal and human geneticists and cell biologists. Originally a zoologist, Adrian Sumner has spent over 25 years studying human and other mammalian chromosomes with the Medical Research Council (UK). One of the pioneers of chromosome banding, he has used electron microscopy and immunofluorescence to study chromosome organisation and function, and latterly has studied factors involved in chromosome separation at mitosis. Adrian is an Associate Editor of the journal Chromosome Research, acts as a consultant biologist and is also Chair of the Committee of the International Chromosome Conferences. The most up-to-date overview of chromosomes in all their forms. Introduces cutting-edge topics such as artificial chromosomes and studies of telomere biology. Describes the methods used to study chromosomes. The perfect complement to Turner.
Book Synopsis Molecular Biology of Chromosome Function by : Kenneth W. Adolph
Download or read book Molecular Biology of Chromosome Function written by Kenneth W. Adolph and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chromosomes have structure, determined by the interactions of proteins with DNA, and chromosomes have functions, in particular, replication of DNA and transcription of messenger RNA. Chromosome structure and function are not separate topics, since chromosome organization pro foundly influences the activity of the genome in replication and transcrip tion. This is especially clear for higher cells, including human cells, in which chromatin fibers are created by the binding of histone proteins to the DNA, and folding of the fibers produces mitotic chromosomes and interphase nuclei. The intricate organization of DNA in higher cells is now recognized as being closely involved with genome activity. Many fundamental results have originated from studies of bacterial and viral systems, which have been systems of choice because of their less complex life cycles. The processes of replication and transcription show differences between the higher and simpler systems (e. g. , different enzymes and protein factors are involved). But the parallels are as striking as the differences in detail. Even for bacteria and viruses, a full understanding of these processes will require integrating the results of molecular biology with those of structural biology and cell biology. Three important subjects are covered in this volume: DNA replication and recombination, gene transcription, and chromosome organization. The sections dealing with replication and transcription examine recent results obtained by applying the techniques of molecular biology and biochemistry. Eukaryotic, prokaryotic, and viral systems are discussed.

Book Synopsis Chromosomal Proteins and Gene Expression by : Gerald R. Reeck
Download or read book Chromosomal Proteins and Gene Expression written by Gerald R. Reeck and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book stems from an Advanced Study Institute on Chromo somal Proteins and Gene Expression that was held in Sitges, Spain, on September 17-26, 1984. It would be misleading to call this volume a conference proceedings, however. The ASI was not a conference, but a course with diverse activities, only one of which was a set of major presentations by the lecturers. Indeed, the concept of lecturer was intentionally obscured as we all learned from each other through shorter presentations by other participants and through seminars, poster sessions, and small group discussions. Furthermore, many participants found that exchanging ideas outside organized sessions was among the most rewarding aspects of the course. Some even claimed to have profitably probed the intricacies of nucleosome structure and transcriptional regulation while basking in the sun on the beachl Obviously, it is difficult to catch the flavor of such varied proceedings in a book. (I cannot confirm the incident on the beach, never having found time to set foot there. Such is the fate of the director of a meeting. ) The ASI was judged a success -- and enthusiastically so - by most participants. Not only did we deepen our understanding of our scientific field, we made new friends and learned about scientific and nonscientific aspects of life in other countries and about issues that transcend international boundaries in our complex world. We hope that this volume will be as successful as the course was.
