RESUMO
In this communication the determination of intermediary nodes in evolutionary dendrograms of proteins is analyzed, based on the molecular mechanisms involved in these transitions and the probability of acceptance of the amino acid substitutions.

The transcription-translation process in the virus-host cell system is analyzed in terms of a virtual neural network. In contrast to findings in the transcription-translation process in eukaryotic cells, an inverse correlation between the frequency of protein amino acids and code degeneracy and between code degeneracy and the rate of amino acid substitutions was not found. Misuse of the virtual host cell network by virus protein synthesis could be attributed to the different amino acid composition of the virus proteins (input unit) studied here.
