Abstract:
Like inanimate matter, biological matter is condensed, though it may be more complex. However, a living cell is a chemically open system with biological functions that are often a nonstationary, nonlinear type of collective phenomena driven by chemical reactants, e.g. ATP, GTP, ligands and receptors. The living cell and many of its subsystems are hence lyotropic systems, depending on various reactant concentrations rather than the temperature. Nonlocal and local correlations of the interacting molecules become the prerequisites for signal transduction. This book constitutes the proceedings of the workshop entitled "Biological Physics 2000". Contents: Biological Physics: An Overview (H Frauenfelder); Protein Folding: Physics on Products of Evolution (N Go); Movements of Molecular Motors (R Lipowsky); Long Range Interaction Between Protein Complexes in DNA Controls Replication and Cell Cycle Progression: The Double Helix and Microtubules Behave Like Elastically Braced Strings (L Matsson); Path Integral Approach to Reaction in Complex Environment: A Bottleneck Problem (V Sa-yakanit & S Boribarn); Nonlinear Approach in DNA Science (L V Yakushevich); Path Integral Approach to a Single Polymer Chain with Excluded Volume Effect (V Sa-yakanit et al.); The Propagation of Electronic Excitation in Molecular Aggregates (J S Briggs); and other papers. Readership: Biophysicists, biochemists, physical chemists, applied physicists and molecular biologists.
