摘要
本文在简述了转录循环和转录中间体、尤其是转录延伸复合物结构的基础上 ,就RNA聚合酶在转录延伸中的作用作了综述。RNA聚合酶对转录调节作出抉择依赖于对转录延伸复合物内在的或外来的信息输入 ,其功能在很大程度上都像是一个信息加工者。
It is reviewed for the function of RNA polymerase during transcription elongation based on the description of transcription cycle and the structure of transcription intermediates,especially, the transcription elogation complex. The decision of RNA polymerase for transcriptional regulation depends on the intrinsic or extrinsic imputs of information to transcription elongation complex. Thus, the function of RNA polymerase looks like an information processor to a great extent.
