Construction of phylogenetic tree based on DNA sequences

Abstract

【Objective】 The study constructed phylogenetic tree based on DNA sequence to analyze the evolutionary process of organism.【Method】 A model and an algorithm were provided for constructing phylogenetic tree based on the principle of maximum likelihood estimate.Firstly,the ML model was given to determine father node,evolutionary time and the relationship between conserved probability and similarity.Then the process of organism evolution was recovered.【Result】 Given a set of DNA sequences,phylogenetic tree can be constructed by our algorithm.Also,the father sequences and the evolutionary time are obtained from the evolutionary tree.【Conclusion】 Phylogenetic trees obtained from our algorithm are rational.Furthermore,the algorithm is simple,and can be used to construct phylogenetic tree in large scale DNA sequences.
