Protein Ordered Sequences are Formed by Random Joining of Amino Acids in Protein 0th-Order Structure, Followed by Evolutionary Process

  • Kenji Ikehara
Origin of Life


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 0th-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.
