Abstract: Based on chaos game representation of DNA sequence,the authors obtain a 6-component vector whose elements are the leading eigenvalues of corresponding measure matrices to represent the DNA sequence.The correlation distances among introduced vectors are applied to compare the similarities of the coding sequences of the first exon of beta globin gene of 11 different species.The results are basically coincident with their evolutionary relationship.

Key words: DNA sequence, chaos game representation, measure, correlation distance, similarity analysis
