Compartmentalization of self-reproducing machineries: multiplication of microsystems with self-instructing polymerization of amino acids.

A theoretical model is presented for the self-instructing polymerization of free amino acids which proceeds inside microsystems which are phase-separated from the solution of thermal polyamino acids. It is shown theoretically that a compartmentalized microsystem fixes inside itself only the process with a faster macromolecular multiplication as time passes, even if the catalytic polymerization alone could spontaneously decrease the corresponding reaction rate. The compartmentalized machinery of macromolecular multiplication cannot reach its stationary state. The machinery is inevitably multiplied and alternates with those with either faster rates of macromolecular multiplication or slower rates of macromolecular degradation during their time development. These results are based upon the dynamic process that any material system acts by itself so as to remove any flow disequilibrium, that is, to maintain the continuity of material flow.
