Abstract

A phylogenetic analysis of a family of related biological sequences is to determinate how the family might have been derived during evolution. Current versions of phylogenetic analysis programs provide three main methods for phylogenetic analysis - parsimony, distance, and maximum likelihood methods--and also include many types of evolutionary models for sequence variation. Most of them make use of multiple alignment of sequences, which doesn't work for all types of data. Here we propose a new method for phylogenetic tree construction from proteins. It is based on characteristic sequence of protein. The proposed method doesn't require sequence alignment and complex algorithm and has reasonably constructed phylogenetic tree for real data set.
