The sliding clamp model of transcription processivity suggests the formation of a highly stable elongation complex ( EC ), in which RNA polymerase is tightly bound to the nascent transcript and template forming the characteristic transcription " bubble ". 在RNA聚合酶Ⅱ介导的转录延伸过程中,其和模板DNA及转录产物RNA紧密结合,形成一个非常稳定的延伸三维复合物(elongationcomplex,EC)。
The paper analyzes the sliding of the straightener of 8 MN tension at the clamp during extension and gets the idea that the main reason is the influence of the slide wedge angle and puts forward some measures to be taken. 分析8MN张力矫直机在拉伸过程中经常出现的钳口打滑问题,其钳口打滑的主要原因是斜滑块角度的影响,分析影响斜滑块角度的因素,并提出解决措施。
