  3. The start reading framae and stop codons, base composition in protein - coding genes and the codon usage of amino acids in scolopendra multilane were compared with the three other myriapods

    本研究在蛋白質編碼基因起始閱讀框和終止密碼子、蛋白質編碼區的堿基組中文摘要成、氨基酸及密碼子的利用等方面把少棘蜈蚣與另三種多足類進行了比較。
  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

    在其起始密碼子上游- 65nt發現桿狀病毒晚期啟動子轉錄起始信號ataag ，在其終止密碼子下游- 14nt發現polya加尾信號aataaa 。
  5. The start codon is at 84 - 86bp, the stop codon at 1658 - 1661bp. the homologous comparison of the deduced amino acid sequence with other plant epsp synthase proteins shows the identity to those of b. napus, a. thaliana, tomato, n. labacum respectively are 92 %, 91 %, 80 %, 65 %

    同源比較該段序列所編碼的氨基酸序列可以發現epsp合成酶有較高的保守性，它與歐洲油菜、擬南芥、西紅柿、煙草的同源性分別為920 、 91o 、 80o 、 65o 。
  6. 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，為典型的嗜鹽古菌啟動子;它的轉錄起始位點距離「 atg 」只有7個核普酸，也是典型的嗜鹽古菌的「卜adless靦script 』 』 。
  7. 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起始密碼子atg上游50位有強晚期啟動子轉錄起始信號ataag ，在? 112位和? 189位存在兩個tatabox ，但未發現早期轉錄信號cagt 。
  8. 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 ）分析結果表明ha122基因的轉錄主要從翻譯起始密碼子上游第47個堿基起始，該處有一個晚期轉錄信號taag 。
  9. Histochemical gus assay showed that the gus staining was observed only in the mature pollen and germination pollen tube. there is no detectable gus activity in other floral organs, leaves and stems. these results suggested that st901 is a novel pollen - specific gene and the 288bp promoter fragment ( - 297 ? xfrom the translation start codon atg ) is sufficient for pollen - specific expression and os - element regulatory of st901 promoter was possibly concentrated in the region - 297 to - 9

    通過對gus酶活性的組織化學定位分析，表明， st901基因啟動子驅動gus基因特異地在成熟花粉和花粉管中表達， st901基因具有花粉表達特性；且288bp （ - 297至- 9 ） （ atg定為+ 1 ）的啟動子區段足以驅動gus基因在花粉中的特異表達， st901基因啟動子的花粉順式表達元件可能位於- 297至- 9之間。
  10. 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

    通過半巢式的基因步移法，經二輪pcr后，從genomewalker文庫分離到2個片段，較大的片段測序表明該706bp序列含有編碼ast的起始密碼子atg ，其上游序列為啟動子序列。
