Quantum mechanical properties of biosystems: a framework for complexity, structural stability, and transformations.
Internal quantum non-demolition measurements are inherent for biological organization and determine the essential features of living systems. Low energy dissipation in these measurements provided by slow conformational relaxation of biomacromolecular complexes (regarded as measuring devices) is the main precondition of enzyme operation and information transfer determining the steady non-equilibrium state of biosystems. The presence of an internal formal description inside a biosystem, expressed in genetic structures (developmental program), is a consequence of its quantum properties. Incompleteness of this formal description provides the possibility of the generation of new functional relations and interconnections inside the system. This is a logical precondition of an evolutionary process. The quantum mechanical uncertainty that underlies the appearance of bifurcations is considered to be the main physical foundation of complication and irreversible transformation of biosystems.
