title: STRUCTURAL ORDER AND PARTIAL DISORDER IN BIOLOGICAL SYSTEMS: Structural "Fuzziness" underlying All Biological Functions creator: Baianu, Prof. Dr. I.C. subject: Statistical Models subject: Dynamical Systems subject: Complexity Theory subject: Neural Nets subject: Theoretical Biology description: The presence of structural order and partial disorder is discussed for several important biological molecules such as DNA, enzymes and proteins, as well as for cellular structures such as nerve myelin. The relationship between structural "fuzziness" and biological function is discussed as an important aspect of biological complexity and biodynamics. The possible effects of partial disorder on the electron density of states in biological structures are predicted based on known quantum theoretical computations for lattices in solids. Important phenomena such as Anderson delocalization, Hall effect and quantum tunneling are predicted to affect biological function. Novel experiments are being proposed by pulsed lasers, pulsed/FT-NMR and optical/NIR spectroscopy to monitor the effects of structural partial disorder and "fuzziness" on biological function. Novel methods for computer analysis of paracrystalline lattices such as nerve myelin and oriented DNA fibers are also proposed based on molecular models that include partial disorder. publisher: Pergamon Press Ltd. contributor: Landahl Sr., Professor H.D. date: 1980-09 type: Journal (Paginated) type: PeerReviewed format: application/pdf identifier: http://cogprints.org/3822/1/letterBMBpdf.pdf identifier: Baianu, Prof. Dr. I.C.
