MOTIVATION Alignment-free sequence comparison methods are still in the early stages of development compared to those of alignment-based sequence analysis. In this paper, we introduce a probabilistic measure of similarity between two biological sequences without alignment. The method is based on the concept of comparing the similarity/dissimilarity between two constructed Markov models. RESULTS The method was tested against six DNA sequences, which are the thrA, thrB and thrC genes of the… CONTINUE READING
