In this paper we propose a matrix depiction and two new invariants of DNA sequences. This approach is illustrated on the primate mitochondrial DNA sequences for 11 different species and 80 different H5N1 avian influenza virus DNA sequences. We also construct the dendrogram tree for them. These phylogenies obtained are generally consistent with evolutionary trees constructed in previous studies.
