查询词典 deoxyribonucleic acid

Ingle nucleotide polymorphism genotying and deoxyribonucleic acid methylation are significant in molecular biology, but their tradition analyse methods have some limitations, and liquid chromatography - mass spectrometry are favourable for analyzing them.

NP分型和DNA甲基化在分子生物学中具有重要的研究意义，但它们传统的分析方法存在较大的缺陷，而液-质联用技术在SNP分型和DNA甲基化分析中显示出良好的应用前景。

Fractal is a subdiscipline of nonlinear area, researches on fractal characteristics of the deoxyribonucleic acid sequence may reveal some secret hidden in the DNA sequence during the process of biological evolution. Chaos Game Representation was proposed as a scale-independent representation for genomic sequences by Jeffrey in 1990. This technique, based on iteration function system, represents the word distribution statistics in DNA sequence as the fractal graphic. Therefore, we can get the distribution of sequence through analysis of fractal theory.

分形是非线性领域的一门分支学科，关于脱氧核糖核酸序列分形特征的研究，可以揭示生物在进化过程中隐藏在DNA序列中的某些秘密。1990年Jeffrey提出了基因组序列的与尺度无关的混沌游戏表示法，这是基于迭代函数系统的一种方法，它将DNA序列中一定长度字的分布规律表现为图形的分形特征，进而通过分形分析就可获取序列的分布规律，从而也成为DNA序列分析的一种统计方法。
