• A new normalized similarity measure is introduced.
• 3D-dynamic representation of DNA sequences is applied for similarity analysis.
• Multidimensionality of the similarity space of DNA sequences is discussed.
Similarity/dissimilarity analysis of DNA sequences is performed using 3D-dynamic representation. The sequences are represented by material points in a 3D-space. Descriptors related to such 3D-dynamic graphs are calculated. A new normalized similarity measure is introduced for a comparison of the sequences. The method is applied to β-globin (HBB) genes of different species. Different methods are compared. The multidimensionality of similarity space of complex objects is discussed (different results for each of the methods). It is also shown that it is easier to find the properties which are consistent with the observation of the evolution of the species for the second exons of β-globin gene rather than for the first ones.
