决定转基因表达的启动子序列

1. 引言 传统的观点认为真核生物基因的表达是由位于同一分子（顺式元件）上的 DNA 序列与不同 DNA 分子（反式作用信号）编码的蛋白质或 RNA 之间的相互作用来调控的。这些顺式作用元件包括 CAAT 框和 TATA 框、启动子本身的响应元件、编码区远上游或下游端的增强子元件、5' 及 3' 非编码区（UTR ) 、内含子、多聚腺苷酸信号等。然而，这个相当简单的观点一直受到怀疑，特别是随着人们对哺乳动物生物学知识了解的逐步深入，该观点也得到更新和完善。（见示例

as proviruses that were cloned from cells infected with a naturally-occurring retrovirus. Although extensive deletions of proviruses were made, vectors retain the cis-acting viral sequences necessary for the viral lifecycle. These include the packaging sequence
