Peptides formed through the mechanism of tRNA dimerization are partially organized. The set of amino acids coming from a tRNA pair have properties correlated with those of the anticodons. The next set in the succession may have characteristics independent from the previous one and a collection of independent pairs will compose a large pool of repetitive peptides each containing one or more types of amino acids. Details of further organizational steps require examination of real proteins and of the genetic code structure, to model a succession of dimers that is relevant to physiology and to the formation of the code. The model also provides a mechanism for the entrance of templates and ribosomes into the system. Various imprints of protein structure and properties, and of the mechanism of protein synthesis, were detected in the structure of the genetic code, indicating that a part of the general structure of the matrix was configured in dependence of protein properties.
