DNA gene sequences are the vectors of biologic genetic information. Z curves of gene sequences can convert character sequences into visual spatial curve, and it can improve the efficiency and accuracy of judging genetic sequences. This paper uses the geometrical center distance matrix of Z curve to analyze and compare gene sequences, and analyzes the effects of primary geometric center and secondary...
