The case for the anticode

The present paper will focus on the developments in our lab related to the origin of the code since the Israel meeting (1,2). Principally these items are: (a) a new set of correlations (3) which include ranked hydrophobicities of amino acids and dinucleotides; (b) binding constants (4) of Phe for the four mononucleotides; and (c) binding constants (5) of Phe, Leu, Ile, Val, and Gly for polyadenylic acid (poly A). The data continue to support a model for the origin of the code based on relationships between amino acids and their anticodons.
