  1.

    結果表明， tn5gusa5插入位點有一定的規律性： tn5gusa5在xcc8004基因組上傾向于插入低gc含量（ 50左右的區域插入密度最高）區段；插入位點的靶序列有一定的特異性，在靶序列的首位鳥嘌呤出現的幾率高，而在靶序列的末位胞嘧啶出現幾率高； tn5gusa5的插入密度與該區段基因的轉錄水平無明顯關系。
  2. However, the cloned promoter had 18 substitution at 18 sites, 22 deletions at 18 sites and 3 insertion at 3 sites between sites 0 - - - 1273 bp which was reported to control temporal - spatial specific expression, and 3 substitution at 3 sites, 6 deletions at 6 sites between - 1095 bp and - 1273 bp, the key functional sequence area, in comparing with known osg6b

    但是與報道的osg6b比較，在決定時空特異性的0 - 1273bp功能區域內，有18處出現18堿基替換， 18處出現22堿基缺失， 3處出現3堿基插入；在核心功能序列區域（ - 1095bp - 1273bp ）內，有3處出現3堿基替換， 6處出現6堿基缺失。
  3. It is possible that exogenous dna fragment integerated into acceptor genome, changing gene base sequence or base deletion or base insertion, inducing to mutant at gene level

    這可能是外源dna片段整合進受體的基因組中，改變基因的順序或者引起基因堿基的缺失、插入，從而在基因水平上發生突變。
  4. It was interested that there was an extra six nucleosides insertion between 1647 - 1652nt ( according to the genomic sequence of la sota strain ), and the sequence were cccccc in f48e9 strain, and tcccac in zj1 strain. in order to test if insertion of this six nucleosides is related with the virulence of nd, two primers were designed to amplify the same fragment of another ten ndv strains. the result of sequence comparison of 16 strains showed that the six nucleoside was absent in lentogenic strain. this suggested that the six nucleosides insertion might have relationship with the ndv virulence. compared with all known sequence of ndv. there was a special sequence ( 5 ' tctctctcctctctcctcc3 " ) in the genomic cdna of ndv f48e9 strain

    通過rt - pcr方法擴增獲得了另外10個背景清楚毒株的np - p基因間隔區片段，將這些序列與f48e9 、 lasota 、 clone30 、 b1 、 zj1和v4的相應序列進行了比較，結果在參比的16個ndv毒株中在該區段中除了有多個點突變外，個別毒株有堿基插入和缺失，所有以lasota株為代表的弱毒株均無6堿基的插入，而以f48e9株為首的強毒株均有此6堿基的插入，但有一個中等毒力的毒株dp沒有6堿基的插入，不過它的基因序列和lasota的幾乎相同，對于所克隆到的基因的代表性還有待確定。
  5. Selenocysteine insertion sequence, secis

    硒半胱胺酸插入序列
  6. After amplifying genomic sequences flanked with tn5gusa5 by tail pcr and dna sequencing, then doing blast with genomic sequence of xcc 8004, insertion sites of 10981 mutants were located precisely in xcc 8004 genome

    經tail - pcr擴增tn5gusa5旁側序列並測序，經與xcc8004基因組序列比對后獲得精確定位的tn5gusa5插入突變體10981個。
  7. According to stratum characteristics, an improved algorithm based on tri - prism model is put forward, in which methods such as core - sequence first are used in process of modeling and the pinch out of stratum is achieved with the insertion of virtual - borehole based on these, simulation of complex overturned stratum is well realized without manual operation

    針對地質體的特點，提出一種三稜柱模型的改進演算法，將核心序列優先等方法運用於建模過程，同時運用虛擬鉆孔柱的方法處理尖滅，在無需人工干預的情況下較好地實現了對復雜地層倒轉現象的模擬。
  8. The results showed : ( 1 ) in the d - loop of mtdna genome from 18 individuals, there were only transition and transversion, were not insertion and deletion, and the frequency of transition was higher than transversion ; ( 2 ) and nucleotide diversity was 0. 0011, the sequence divergence values among haplotypes was 0. 005

    研究結果顯示： （ 1 ） 18隻大鴇的301bp - 330bpmtdna控制區序列的突變只有轉換和顛換，無插入和缺失，且轉換的頻率高於顛換； （ 2 ）核苷酸多態性只有0 . 0011 ，不同單元型間的序列差異值為0 . 5 。
  9. And the two pah ' s of pcr primers that bind to the adapter and the sequence of f fragment close by tn5 respectively were also designed. the genomic dna of b8 was isolated, digested with bamh i, and ligated to the adapter. using the two pairs of the primers, two rounds of pcr were performed hi turn and a fragment of 239bp was amplified successfully. lt was proved by cloning and sequencing that 18bp of the fragment is the sequence opposite to f fragment on the left of tn5 insertion site in b8f, the other is part of the 728 bp of f fragment. this result makes it possible to continue to carry out chromosome walking, to clone and sequence the whole genes of b fragment and f fragment, and to reveal the antagonistic molecular mechanism of b8

    試驗研究設計併合成了由40和44個堿基的寡聚脫氧核苷酸組成的染色體爬行接頭，在接頭序列和測定的f片段近tn5的序列上，設計了2對染色體爬行用的pcr引物，從b8菌株中提取基因組dna ， bamhi酶切，與染色體爬行接頭連接，依次用2對引物進行pcr ，擴增出239bp產物，經克隆、測序，發現其中18bp為擴增的相應于f片段在b8f菌株tn5插入位點對面的序列，其餘則為f片段728bp序列的一部分，為進一步進行染色體爬行，克隆和測定整個b和f基因，揭示陽菌株的拮抗分子機制提供了技術資料貯備。
