Single molecule techniques, including single molecule fluorescence, optical tweezers, and scanning probe microscopy, allow for the manipulation and measurement of single biological molecules within a live cell or in culture. These approaches, amongst the most exciting tools available in biology today, offer powerful new ways to elucidate biological function, both in terms of revealing mechanisms of action on a molecular level as well as tracking the behaviour of molecules in living cells. This book provides the first complete and authoritative treatment of this rapidly emerging field, explicitly from a biological perspective.The contents are organized by biological system or molecule. Each c...
DNA in the nucleus of plant and animal cells is stored in the form of chromatin. Chromatin and the Chromatin remodelling enzymes play an important role in gene transcription.
Scanning Probe Microscopy (SPM) is the enabling tool for nano(bio)technology, which has opened new vistas in many interdisciplinary research areas. Concomitant with the developments in SPM instrumentation and techniques are new and previously unthought-of opportunities in materials nanofabrication and characterisation. In particular, the developments in addressing and manipulating matter at the level of single atoms or molecules, and studies of biological materials (e.g. live cells, or cell membranes) result in new and exciting discoveries. The rising importance of SPM demands a concise treatment in the form of a book which is accessible to interdisciplinary practitioners. This book highligh...
A representative cross-section of elastic biomolecules is covered in this volume, which combines seventeen contributions from leading research groups. State-of-the-art molecular mechanics experiments are described dealing with the elasticity of DNA and nucleoprotein complexes, titin and titin-like proteins in muscle, as well as proteins of the cytoskeleton and the extracellular matrix. The book speaks particularly to cell biologists, biophysicists, or bioengineers, and to senior researchers and graduate students alike, who are interested in recent advances in single-molecule technology (optical tweezers technique, atomic force microscopy), EM imaging, and computer simulation approaches to study nanobiomechanics. The findings discussed here have redefined our view of the role mechanical signals play in cellular functions and have greatly helped improve our understanding of biological elasticity in general.
A comprehensive volume that brings together authoritative overviews of single molecule science techniques from a biological perspective.
More than 40 years after the discovery of the nucleosome as the fun- mental unit of chromatin, the multifaceted problem of how variations in ch- matin structure affect the activity of the eukaryotic genome has not been solved. However, during the past few years research on chromatin structure and fu- tion has gained considerable momentum, and impressive progress has been made at the level of concept development as well as filling in crucial detail. The structure of the nucleosome has been visualized at unprecedented reso- tion. Powerful multisubunit enzymes have been identified that alter histone/ DNA interactions in ways that expose regulatory sequences to factors initi- ing and regulating ...
Praise for the Serial:"Full of interest not only for the molecular biologist - for whom the numerous references will be invaluable - but will also appeal to a much wider circle of biologists, and in fact to all those who are concerned with the living cell."--British Medical Journal - Provides a forum for discussion of new discoveries, approaches, and ideas in molecular biology - Contributions from leaders in their fields - Abundant references
Propelled by the success of the sequencing of the human and many related genomes, molecular and cellular biology has delivered significant scientific breakthroughs. Mathematics (broadly defined) continues to play a major role in this effort, helping to discover the secrets of life by working collaboratively with bench biologists, chemists and physicists. Because of its outstanding record of interdisciplinary research and training, the IMA was an ideal venue for the 2007-2008 IMA thematic year on Mathematics of Molecular and Cellular Biology. The kickoff event for this thematic year was a tutorial on Mathematics of Nucleic Acids, followed by the workshop Mathematics of Molecular and Cellular ...
An essential resource for all scientists researching cellular responses to DNA damage. • Introduces important new material reflective of the major changes and developments that have occurred in the field over the last decade. • Discussed the field within a strong historical framework, and all aspects of biological responses to DNA damage are detailed. • Provides information on covering sources and consequences of DNA damage; correcting altered bases in DNA: DNA repair; DNA damage tolerance and mutagenesis; regulatory responses to DNA damage in eukaryotes; and disease states associated with defective biological responses to DNA damage.
