Organization of human chromosomes


Book Description

Since 2012, thousands of human genomes have been completely sequenced, and many more have been mapped at lower levels of resolution. The resulting data is used worldwide in biomedical sciences, anthropology, forensic medicine and other branches of science. Recent results suggest that most of the vast amounts of non-coding DNA within the genome have associated biochemical activities, including regulation of gene expression, organization of chromosome architecture and signals that control epigenetic inheritance. Summary of the contents of this book: Organization of human chromosomes Nuclear organization and rearrangements in pluripotent cells Organization of the human genome Repetitive elements and human disorders Mitochondrial DNA Cell division The cell cycle The phases of mitosis The human karyotype Karyotype analysis Types of staining Meiosis Cytokinesis The Second Meiotic Division (Meiosis II)







Chromosomes


Book Description

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.

This new edition continues to cover both basic and up-to-date material on normal and defective chromosomes, yet is particularly strengthened by the complete revision of the material on the molecular genetics of chromosomes and chromosomal defects. The mapping and molecular analysis of chromosomes is one of the most exciting and active areas of modern biomedical research, and this book will be invaluable to scientists, students, technicians and physicians with an interest in the function and dysfunction of chromosomes.




Mapping and Sequencing the Human Genome


Book Description

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.




Human Chromosomes


Book Description

"This book provides an introduction to human cytogenetics. It is also suitable for use as a text in a general cytogenetics course, since the basic features of chromosome structure and behavior are shared by all eukary otes. Because my own background includes plant and animal cytogenet ics, many of the examples are taken from organisms other than the human. Since the book is written from a cytogeneticist's point of view, human syndromes are described only as illustrations of the effects of abnormal chromosome constitutions on the phenotype. The selection of the phenomena to be discussed and of the photographs to illustrate them is, in many cases, subjective and arbitrary and is naturally influenced by my interests and the work done in our laboratory. " The above paragraph from the Preface of the first edition of this book also fits the present edition. However, so much has happened in five years in cytogenetics that-apart from a couple of pages here and there-the whole book has been rewritten and nine new chapters have been added. The system used in the first edition to cite, whenever possible, the latest and/or the most comprehensive review rather than the original publica tions has been followed here also. Not only would complete literature citations increase the size of the book too much, but many readers have expressed satisfaction with the referencing method used here.




Molecular Structure of Human Chromosomes

Practical Genetics for the Ob-Gyn


Book Description

Understand the clinical application of genetics in ob-gyn practice with this case-based text This up-to-date resource surveys the modern field of genetics and provides you with a practical understanding of its clinical uses. Whether determining who is pre-disposed to disease, how a patient will respond to therapy, or what the optimal cancer treatment might be based on tumor profiles, this is the only guide to help efficiently interpret and utilize genetic data across the full spectrum of ob-gyn clinical scenarios. Practical Genetics for the Ob-Gyn is organized around three central themes: basic genetic principles, clinical applications of ob-gyn practice, and common methods of genetic testing. Opening each chapter is a patient case study that establishes a realistic clinical context for the subsequent genetics-based material addressed.




Human Interphase Chromosomes


Book Description

This second edition focuses on the study of human interphase chromosomes and its relation to health and disease. Orchestrated organization and behavior of the human genome in interphase nuclei at chromosomal level has been repeatedly shown to play a significant role in almost all basic biological processes involved in the processing and inheritance of genetic information within and between species. Accordingly, post-genomic bioscience appeals to basic and applied studies of interphase nuclei genetics and genomics with special attention to interphase chromosome behavior in health and disease. Additionally, elucidating the role of interphase chromosome behavior during development, chromosome/DNA replication, DNA reparation opens new horizons for basic and applied bioscience Studies of interphase nuclei have an appreciable impact on different areas of biomedical sciences such as cell biology, neurobiology, cancer research, developmental biology, epigenetics, cytogenetics, and medical genetics, as a whole. Moreover, development of innovative and emergent technologies to analyze interphase nuclei are closely associated with application of these techniques in diagnostic and research practices to solve reproductive problems (including infertility and spontaneous abortions), to investigate congenital malformations (including those produced by aneuploidy and other chromosome abnormalities); genetic diseases (including cardiac, immune, neurological and psychiatric diseases), and cancer. This second edition serves as a source of updated valuable information and promising ideas for a wide audience of professionals in biomedicine including researchers, scientists, and healthcare professionals in human genetics, cytogenetics, and developmental biology.
