title: A new approach for the cooperative chemical evolution of nucleic acids and proteins under the primitive earth environment.
abstract: In order to evaluate cooperative chemical evolution of nucleic acids and proteins, we have examined possible activity of thermal copolymers of amino acids (TCAA) for prebiotic formation and degradation of RNA. Several types of TCAA involving aromatic amino acids were prepared and the influence on the template-directed formation of oligoguanylate and prebiotic ribonuclease activity were kinetically studied.
