In this paper we (1) introduce a directed graphical representation of DNA primary sequences; (2) describe a scheme that transforms the directed graph of a DNA sequence into an upper triangular matrix; (3) investigate whether or not the existing matrix-based invariants of DNA sequences are compatible for the upper triangular matrix representation. The utility of our method is illustrated by an examination of the similarity between human and other seven species.
在本文中，我们（1）介绍了一种DNA一级序列的有向图形表示；（2）描述了一种将DNA序列的有向图转换为上三角矩阵的方案；（3）研究了现有的基于矩阵的DNA序列不变量是否与上三角矩阵表示兼容。通过检查人类与其他七个物种之间的相似性来说明我们方法的实用性。
