摘要:
DNA序列作为一种复杂的遗传信息,其具体特性不仅体现在编码序列之中,也包含在非编码序列之中。在高等生物体中主要基因成分为非编码序列,在ENCODE计划中,有证据表明,在人类基因中有98%为非编码形式,其中80%具有功能性,所以对编码区和非编码区的研究已经成为一类重要研究热点。本文提供的模型和实验结果,使用图形表示方法对编码区以及非编码区基因的差异进行区分。该模型采用的是对编码区以及非编码区的DNA序列进行分段概率测量,从而对不同的基因特征分布进行比较。
Abstract:
DNA sequences include complex genetic information; their specific characteristics are contained in both the coding and non-coding sequences. Major gene components in higher levels of organisms are composed of non-coding sequences. In ENCODE project, there are evidences that 98% of the human genomes are non-coding forms and 80% of them with functions, so the research on coding region and non-coding region has become an important research hotspot. This paper provides models and experiment results which using visual representation techniques to distinguish differences between coding and non-coding sequences. This model uses probability measurements on the DNA sequences to coding and non-coding regions respectively to distinguish patterns identified from different sequences.
