Phylogenetic comparison of genes using long range correlation patterns in DNA sequences

摘要

The diversity of life is staggering which is apparent not only in the large number of species, but also in their heterogeneity. Species share commonalities based on their physical appearance, but the intrinsic similarities lies within their DNA sequences which point towards relationships of evolutionary descent. In the proposed research, the authors have analyzed the phylogenetic relationships between genes of different species using the long-range statistical correlation patterns. It is found that the genes of species which are considered to be evolutionarily related are in fact similar in their long-range correlation patterns which provide a substantial proof of their evolutionary relationship.
