[Strategy of synonymous codon usage in encoding sequences of the tick-borne encephalitis virus].

Three basic genotypes of the tick-borne encephalitis virus have wide geographical spread; several strains have local spread. In this work, we studied the strategy of the synonymous codon usage in basic genotypes by means of calculation of relative synonymous codon usage values for each complete encoding sequences of viruses. Then, these values were analyzed by methods of the discriminant analysis. In the result of this work the conclusion about the available distinctions in the strategy of synonymous codon usage of various genotypes tick-borne encephalitis viruses was made.
