title: Protein ordered sequences are formed by random joining of amino acids in protein 0(th)-order structure, followed by evolutionary process.
abstract: Only random processes should occur on the primitive Earth. In contrast, many ordered sequences are synthesized according to genetic information on the present Earth. In this communication, I have proposed an idea that protein 0(th)-order structures or specific amino acid compositions would mediate the transfer from random process to formation of ordered sequences, after formation of double-stranded genes.
