| 1. | Chain initiating codon 链起始密码子 |
| 2. | In order that bar gene efficiently transcript and translate in eukaryote , the sequence next to atg was modified by pcr 为了目的基因在真核生物中有效的翻译和表达,通过pcr方法对bar基因起始密码子atg旁侧序列进行改造。 |
| 3. | ( 2 ) at translation level plant mutual sequence of starting translation aaca was added to start codon of t - pa gene by pcr ampliation and plant expression vector pbet was constructed ( 2 )在翻译水平上通过pcr扩增的方式在t - pa基因起始密码子处添加了植物翻译起始共有序列aaca ,构建了植物表达载体pbet 。 |
| 4. | 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 。 |
| 5. | The sequence encodes an open reading frame of 518 amino acids . there is a transit peptide of 74 amino acids in the n terminal of the putative amino acids sequence coded by the cdna 该序列长为1758hp ,起始密码子位于84 86hp ,终止密码子为1658 166fop ,开放阅读框长为1557hp ,编码58个氨基酸序列,其中n末端含有74个氨基酸的转运肽。 |
| 6. | 5 ' race analysis indicated that ha 122 transcripts start predominantly in the consensus major late transcription initiation motif rtaag around 47nt upstream of the putative translation start codon with a minor start at position - 89 5 ’ race ( rapidamplificationofcdnaend )分析结果表明ha122基因的转录主要从翻译起始密码子上游第47个碱基起始,该处有一个晚期转录信号taag 。 |
| 7. | By using the method of genome walking , two fragments were cloned from genome walker library after the semi - nested pcr . the result of sequencing the bigger fragment showed that this 706bp sequence contained the atg start codon 通过半巢式的基因步移法,经二轮pcr后,从genomewalker文库分离到2个片段,较大的片段测序表明该706bp序列含有编码ast的起始密码子atg ,其上游序列为启动子序列。 |
| 8. | 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 。 |
| 9. | After sequencing of 84 cdna clones and removing redundant cdnas , we obtained 36 cold - regulated unique cdna clones . 12 cdna clones were expected to be novel genes , because no sequence homology with any known sequences was found in genbank databases 全长基因ej175共有603bp ,对其可读阅读框架进行分析,从57 - 515位核苷酸的一段序列,包含了起始密码子和终止密码子,编码152个氨基酸的多肽。 |
| 10. | 2 . the sequence of si gene from ibv - lx4 strain was consisted of 1614 bp from initiation codon atg to the possible cleavage site of spike glycoprotein , encoding for a 18 - amino signal - peptide with the n terminus of si protein and a polypeptide of 537 - amino acids . 19 highly conserved , potential glycosylation sites and 17 cysteines residues were characterized with si protein , homology analysis showe that there were gene deletion - S1基因:其全序列共1614bp (从起始密码子atg到s前体蛋白裂解位点) ,编码537个氨基酸,其氨基端有一编码18个氨基酸的信号肽序列,第12 13位氨基酸残基构成了信号肽的切割位点, 14 19位与111 124位氨基酸残基为s1蛋白的跨膜区域。 |
