Chromatin and Chromosome Structure consists of chapters that reflect a 1975 seminar course and the reported observations after the session. The seminar is organized for the benefit of both faculty and students in the Biology Ph.D. Program of the City University of New York. This book begins with a presentation of the conformational studies of histones. It then describes the histone-DNA interactions and the subunits isolated either from chromatin or from nuclei. It also explains the post-synthetic modifications of histone structure. Furthermore, the book talks about the chemistry and function of nuclear nonhistone proteins, low molecular weight nuclear RNA, and polytene chromosome structure. The regulation of gene expression in chick oviduct model system and the main features of lampbrush chromosomes are shown as well. Aside from the students and faculty of the above-mentioned university, this compilation will be invaluable as well to other undergraduate and graduate students; professors; and researchers. It will also be a good reference to those who are specializing in chromatin and chromosome studies.

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.

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.

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.

The DNA of eukaryotes is packaged into chromosomes - each chromosome consisting of a very long molecule of DNA and various proteins (e.g. histones), and the number of chromosomes being characteristic for the species concerned. Chromosome analysis can provide a great deal of information for many aspects of cellular genetics such as DNA replication, protein:DNA interactions and genetic manipulation. The book is structured in a methodical fashion - the introductory chapters are centred around analysis of chromatin with chapters on the mapping of protein:DNA interactions in vivo using ligation-mediated PCR and the mapping of chromatin-associated proteins by formaldehyde cross-linking. The next chapters concentrate on the study of whole chromosome structure, including: fission yeast chromosome analysis using FISH and CHIP, isolation of vertebrate metaphase chromosomes and their analysis by FISH, the study of vertebrate chromosome progression through mitosis, and the analysis of mammalian interphase chromosomes by immunofluorescence and FISH. There then follow chapters on FISH in whole-mount tissues and the analysis of the sub-structure of mammalian nuclei in vitro. The final two chapters deal with the experimental manipulation of chromosome structure, including: chromosome assembly in vitro using Xenopus egg extracts and chromosome fragmentation in vertebrate cell lines. This comprehensive and informative laboratory manual includes a diverse range of experimental models for the analysis of chromosomes - such as vertebrates, Drosophila, yeast and Xenopus. Fully illustrated, it focuses on modern techniques and approaches to the study of chromosome structure and will be invaluable to researchers and academic staff in genetics, biomedical science and molecular biology.
