Abstract: In order to explore the relationship between biological layers,from complex bacterial communities to various species and genera,full sequence DNA sequencing has developed vigorously,and the need for visualization of scientific calculation data of various biological gene sequences has become increasingly urgent.The complementary symmetry between the double helix structure of DNA sequence and the complex structure of space is of great significance for exploring a large number of long DNA sequences.Starting from the core idea of “sequence determines structure and structure determines function”,this paper uses a measurement model and method based on variant value system to analyze and compare the complete DNA sequences of two kinds of bacteria,bacillus and Mycobacterium by using the method of combination of information technology and statistics,showing their two-dimensional characteristic distribution of DNA sequences.The visual form shows the similarities and differences between the two kinds of bacteria.Compared with the traditional bacterial visualization method,this method has the characteristics of low time complexity,good stability,strong intuition and easy to understand.A series of distribution diagrams are provided under different measurement reference options.

Key words: DNA, Gene sequence, Measurement model, Variant system, Visualization
