通过对真核生物１４２个基因的部分启动子序列的折叠模型进行分析研究，结果表明，这些基因的ＴＡＴＡ框在折叠结构模型中所表现的茎环结构特征有利于与反式作用因子和ＲＮＡ聚合酶的识别及其相互作用。
By analyzing the folding patterns of partial promoter sequences of 142 genes in eukaryotes, the results show that the structural characteristics of the stem-loops exhibited by the TATA boxes of these genes in the folding structure model are favorable for the interaction with trans-acting factors and RNA polymerisation Identification of enzymes and their interactions.
