转录起始 meaning in English
transcription initiation
Examples
- 2 . specific mutation from a to c at - 137 bp site upstream from transcription start point had no effect on the inducibility of the promoter in response to sa and bth . 3
在转录起始点上游137bp定点将a突变为c后，对化学启动子的化学诱导应答性没有明显的影响，但对诱导效应的向上运输存在一定程度的阻抑作用。 - A late baculoviral transcription initiation motif ataag was found 65 nt upstream of the putative translational start site and a polyadenylation signal aataaa was identified 14 nt downstream of the taa stop codon
在其起始密码子上游- 65nt发现杆状病毒晚期启动子转录起始信号ataag ，在其终止密码子下游- 14nt发现polya加尾信号aataaa 。 - Activity of each construct was determined . the basal promoter was located at about 60bp up stream of the transcription initiation site . it contains a tata box at - 33bp which is required for the transcription initiation
基因的基本启动子元件位于转录起始位点上游约60bp ，其中含有一个位于- 33bp处的tatabox ，它对于转录起始起着重要作用。 - A late transcriptional motif , ataag , was found at - 50nt upstream of the translational start codon atg , while two tata box was located at - 112nt and - 189nt upstream of atg . a typical poly ( a ) signal was found at 12nt downstream of the translational stop codon
在hel起始密码子atg上游50位有强晚期启动子转录起始信号ataag ，在? 112位和? 189位存在两个tatabox ，但未发现早期转录信号cagt 。 - The ie 180 mutant combined with two special protein binding - sites and inhibited the promoter transcription . accidentally in the approach showed that the plasimd pcdna3 show as activator to sv40 and cmv early promoter . the result is acquired by instantaneous transinfect
这说明不同的ie180突变体，对于sv40启动于这类在转录起始位置一侧只有一个“ 5 ’ atcgt 3 ’ ”特征蛋白质结合序列的11类基因启动于，可分别表现出抑制活性与激活性。
