摘要:

由于DNA序列双螺旋结构的互补对称性质以及空间上的复杂结构,探索长距离DNA片段的匹配特征尤其是在互补关系上有着重要的意义。本文利用子串–互补串匹配技术通过对DNA序列已有结构的检测分析着重对回文序列、发夹结构等可能存在的结构进行预测。通过统计测量的方法对DNA数据进行处理,对结果进行对比分析,将测量数据转换为可视图,对批量复杂DNA序列的提取特征数据进行可视化分析。通过结果图示,可以看到选择的DNA序列中的确存在着长距离匹配结构。文中给出的可视化方法,提出的分析测量模型以及提取的测量特征可视化机制能为后续不同DNA序列数据以及结构的可视化分析的应用研究提供坚实的模型和实践基础。

Due to the complementary symmetry properties of the double helix of DNA sequence and complicated space structure, exploring long-range DNA pieces matching characteristics, especially on the complementary relationship has important significance. In this paper, the substring-complementary string matching technique is used to predict the possible structure of hairpin structure and detect palindromic structure in DNA sequences. With using statistical measurement method to processing DNA, and comparing with the results of analysis, visualization of measured-date, large amounts of complex DNA sequences can be analyzed speedy. Through the results, the matching structure in selective DNA sequence does exists in long distance. Visualization methods, the analysis of the characteristics of the measuring model and extract visual mechanism given in the paper can provide a model and practice foundation for different DNA sequence data, and the application of visualization analysis of structure research.
