Abstract
We introduce a graphical representation of DNA primary sequences by taking four special vectors in a 3-D space to represent the four nucleic acid bases in DNA sequences, so that a DNA primary sequence is denoted in a 3-D space by a successive vector sequence which is a directed walk on the space. It is demonstrated that this representation has no overlap and intersection and allows numerical characterization.
摘要
我们通过在三维空间中采用四个特殊向量来表示DNA序列中的四种核酸碱基，从而引入了一种DNA一级序列的图形表示方法，这样，一个DNA一级序列在三维空间中就由一个连续的向量序列表示，该向量序列是空间中的一条有向路径。结果表明，这种表示方法没有重叠和交叉，并且允许进行数值表征。
