title: Abiotic origin of biopolymers.
abstract: A variety of methods have been investigated in different laboratories for the polymerization of amino acids and nucleotides under abiotic conditions. They include (1) thermal polymerization, (2) direct polymerization of certain amino acid nitriles, amides or esters, (3) pi, Tokyo 194, Japan.
