| 4. | By artificially changing a to c at - 137 bp site upstream from transcription start point of cloned promoter , two site - mutation promoters , ipms ( 603 bp ) and ipm1 ( 900 bp ) were created 通过pcr方法对克隆的两个启动子进行定点突变,使转录起始位点上游- 137bp处a突变为c ,得到两个突变启动子( ipml 、 ipms ) 。 |
| 5. | Uppsala university scientists have discovered an entirely new process in which short , tiny " antisense rna " competes with the protein - producing ribosomes for starting sites for reading messenger rna 乌普萨那大学的科学家们发现了一个全新的进程,在短期内,微小的“反义核糖核酸”具有与制造蛋白质的核糖体竞争信使rna起始位点的能力。 |
| 6. | 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。 |
| 7. | 900 bp promoter - directed gus expression was highly induced by sa and bth , while the 603 bp promoter , whether mutated or not , did not respond to sa and bth induction , which indicated that the element in response to sa and bth lied among 575 ~ 872 bp from transcription start site 全长900bp启动子能够应答sa和bth的诱导,而603bp长的启动子无论突变与否对sa和bth均无应答,证明sa和bth的应答区域在克隆启动子的转录起始位点上游575 872bp之间。 |
| 8. | The pa7 fragment was sequenced and several motifs similar to prokaryotic promoter elements such as - lobox , - 35box and up box were found . the sd sequence which was bound by ribosome and atg site were also found . the pat fragment was blast in genebank , but there is no its " homological sequence 对pa7片段的序列分析发现其距5 ’端931bp ? 1091bp处具有原核生物典型基因启动子的保守结构- 10区和- 35区,以及翻译必需的sd序列和翻译起始位点等。 |
| 9. | In order to use the responding ability to the inducers of pr - la promoter , two fragments , ip1 ( 900 bp ) and ips ( 603 bp ) were cloned from tobacco genomic dna by polymerase chain reaction ( pcr ) with primers designed according to the sequence reported in genbank . sequence analysis of the amplified 900 bp fragment indicated that the cloned sequence had 99 % of homology to the known sequence . its transcription start site , tata box and consensus sequence " tgac " conserved in pr genes were identical to those of pr - la promoter 根据pr - 1a基因的报道序列,设计两对引物,以烟草基因组为模板,通过pcr扩增得到900bp ( ipl )和603bp ( ips )两个目标片段,序列测定表明克隆的启动子与报道序列具有99的同源性,转录起始位点、 tatabox及保守序列tgac与报道序列均完全相同。 |
| 10. | The entire halcs gene is located on a megaplasmid and contains a 849 - bp open reading frame that encodes a polypeptide of 283 amino acids . the promoter is typically haloarchaeal , but the start site of transcription is only seven bases from the 5 ' end of the initiator aug codon , making the halcs transcript another example of a " leadless transcript " in the haloarchaea 它的一29一24位置上是一“毛幻人” box序列,为典型的嗜盐古菌启动子;它的转录起始位点距离“ atg ”只有7个核普酸,也是典型的嗜盐古菌的“卜adless腼script ’ ’ 。 |
