Book Description
Within the past two decades, extraordinary new functions for the nucleolus have begun to appear, giving the field a new vitality and generating renewed excitement and interest. These new discoveries include both newly-discovered functions and aspects of its conventional role. The Nucleolus is divided into three parts: nucleolar structure and organization, the role of the nucleolus in ribosome biogenesis, and novel functions of the nucleolus.
The Nucleolus
The Nucleolus and Ribosome Biogenesis
Author: A.A. Hadjiolov
Publisher: Springer Science & Business Media
ISBN: 3709187427
Category : Science
Languages : en
Pages : 281
Book Description
The nucleolus had consistently attracted the attention of investigators in the fields of cell biology and pathology. Because of its ubiquitous presence in the nucleus of eukaryotic cells, its rapid changes during their life cycle, and its rapid response to noxious agents, this organelle has been the subject of a large number of studies. Yet, the exact function and the very reason for the existence of the nucleolus (the only large cellular structure not delimited by a membrane) remain largely unknown. The ribosomes were discovered relatively late in the study of cells, but due to their crucial involvement in the protein synthesis machinery of all living organisms, the elucidation of their structure and function quickly became one of the major goals of molecular biology. The relatively simple structure of the ribosome strengthens the hope that a full understanding of the structure and function of this organelle in molecular terms is within the reach of contemporary research~ Since each of the rRNA and protein molecules embodied in the ribosome is the product of a distinct gene, studies on the biogenesis of ribosomes expanded rapidly to become a core topic in molecular genetics.

ISBN: 3527326987
Category : Science
Languages : en
Pages : 597
Book Description
By way of its clear and logical structure, as well as abundant highresolution illustrations, this is a systematic survey of the players and pathways that control genome function in the mammalian cell nucleus. As such, this handbook and reference ties together recently gained knowledge from a variety of scientific disciplines and approaches, dissecting all major genomic events: transcription, replication, repair, recombination and chromosome segregation. A special emphasis is put on transcriptional control, including genome-wide interactions and non-coding RNAs, chromatin structure, epigenetics and nuclear organization. With its focus on fundamental mechanisms and the associated biomolecules, this will remain essential reading for years to come.

Chromosomes
Author: Adrian T. Sumner
Publisher: John Wiley & Sons
ISBN: 0470695226
Category : Science
Languages : en
Pages : 304
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.

The Functional Nucleus
Author: David P. Bazett-Jones
Publisher: Springer
ISBN: 3319388827
Category : Science
Languages : en
Pages : 501
Book Description
This book gives an in-depth overview on nuclear structure and function. It clearly shows that the epigenome and the three-dimensional organization of the nucleus are not independent properties. The intimate relationship between the location and the epigenetic modifications of gene loci is highlighted. Finally, it shows that the complex three-dimensional organization of the nucleus is not just of academic interest: The structure, composition and function of virtually all of the sub-nuclear compartments identified so far can be implicated to a list of human genetic diseases. Hence, a detailed elucidation of how these domains are assembled and function will provide new opportunities for therapeutic intervention in clinical practice.

Pre-mRNA Processing
Author: Angus I. Lamond
Publisher: Springer Science & Business Media
ISBN: 3662223252
Category : Science
Languages : en
Pages : 230
Book Description
he past fifteen years have seen tremendous growth in our understanding of T the many post-transcriptional processing steps involved in producing func tional eukaryotic mRNA from primary gene transcripts (pre-mRNA). New processing reactions, such as splicing and RNA editing, have been discovered and detailed biochemical and genetic studies continue to yield important new insights into the reaction mechanisms and molecular interactions involved. It is now apparent that regulation of RNA processing plays a significant role in the control of gene expression and development. An increased understanding of RNA processing mechanisms has also proved to be of considerable clinical importance in the pathology of inherited disease and viral infection. This volume seeks to review the rapid progress being made in the study of how mRNA precursors are processed into mRNA and to convey the broad scope of the RNA field and its relevance to other areas of cell biology and medicine. Since one of the major themes of RNA processing is the recognition of specific RNA sequences and structures by protein factors, we begin with reviews of RNA-protein interactions. In chapter 1 David Lilley presents an overview of RNA structure and illustrates how the structural features of RNA molecules are exploited for specific recognition by protein, while in chapter 2 Maurice Swanson discusses the structure and function of the large family of hnRNP proteins that bind to pre-mRNA. The next four chapters focus on pre-mRNA splicing.
