    採用dnastarpackage中的editseq軟體進行序列編輯、 orf查找；採用clustalx軟體進行序列比對（ alignment ） ；比對結果輸入mega2 . 1軟體計算各樣品間的遺傳距離，並基於kjmura2 - parameter模型，用鄰接法（ neighbor - jojning ， nj ）構建系統發生樹，通過自展（ bootstrap1000次）檢驗獲得系統樹分支的置信度。
  5. In our laboratory, a unique mutation detection system using a shuttle vector plasmid has been established to demonstrate that a low concentration of mnng ( 0. 2 m ) can induce nontargeted mutation in mammalian cells : the mammalian cells were exposed to 0. 2m mnng for 2. 5h, then a shuttle plasmid pz189 carrying supf trna gene was transfected into cells after 24h culture. we found a 5 - fold higher mutation frequency of the plasmid replicated in pretreated cells than the spontaneous mutation frequency of the plasmid replicated in control cells. this kind of mutation did not occur immediately after mnng exposure

    我們實驗室曾用一特殊的突變檢測系統，直接證明dna損傷劑可在哺乳動物細胞誘發非定標性突變：首先用低濃度（ 0 . 2 m ）的短壽烷化劑mnng （半壽期為1 . 1hr ）處理細胞2 . 5h后，繼續培養24h ，將重組有用作突變檢測的靶基因supftrna基因的穿梭質粒pz189轉入細胞復制，發現在未受致癌物直接攻擊的穿梭質粒中有較自發突變率高5倍以上的靶基因突變。
  6. The partial sequences of the mitochondrial co i, co ii and trna gene of the adults and larvae of 4 species from lepidostomatidae and the adults and larvae of apsilochorema unculatum and a. hwangi were sequenced and compared in this study. in the sequences obtained ( 1718 ~ 2239bp ), a % + t % was about 69. 2 %, 267 nucleotide sites were substituted in apsilochorema and 266 nucleotide sites were substituted in lepidostomatidae. at bias in the third codon position site was much higher than the other two sites, reaching about 81. 9 %

    {的比對分析表明:在coi區的一45一個比對位點中，有1260個保守位點， 191個變異位點，其中98個轉換位點， 93個顛換位點;發生在密碼子第三、第一和第二位點的變異分別為78 % 、 18 %和4 % ;種內序列歧異度為o一0 . 9 % ，而種間為一4 %一24 % 。
  7. Direct damage on supf trna gene can be neglected because half - life of mnng is 1. 1 hour and the interval between treatment and transfection was as long as 12 - 24 hours. therefore the mutagenesis is not lesion directed

    20m的mnng經洗滌后的極微量殘留經過10 ? 20多個半衰期的降解后，己不足攻擊轉人的qdna分子，因此這種突變顯然是發生在mnng直接攻擊部位以外的正常堿基上。
  8. The results show that there are 7 strains hpi positive except 1 strain hpi negative. hpi in 6 strains of 7 hpi - positive strains is inserted into asnt - trna site. the expression of fyua gene, which encoded fyua, the receptor of ybt, was upregulated by extracellular ybt level

    研究結果提示，除1株eaggec中國分離株hpi 」外，其餘7株均為hpi且7株中有6株攜帶的hpi毒力島均插入在染色體的asnttrna位點。
  9. The immediate transcript of a trna gene is known as precursor trna

    Trna基因的直接轉錄物叫做trna前體。
  10. Hisityl - trna synthetase catalyzes the aminoacylation of trnahis in the initial step of protein biosynthesis. the involumen of histidyl - trna synthetase in autoimmune diseases is another feature of the enzyme. in studies, it is reported that purified jo - 1 antigen can increase the detection rate of anti - jo - 1 antibody. but it is difficult to obtain a single component by biochemical extraction. genetic engineering can help us to desolve this problem. after looking up mrna sequence encoding histidyl - trna synthetase in genebank, we used rt - pcr technology to gain its full length dna sequence. the vestor ptybllwas used in the construction of expressing vestor. we transformed the jo - 1 gene into er2566 and used this system to express fusion jo - 1 antigen

    本實驗從人胎盤中提取總rna ，利用rt - pcr技術獲得了編碼jo - 1的基因整長序列，選用impact - cn系統中的ptyb11載體，構建了jo - 1基因的克隆與表達載體，並轉化大腸桿菌er2566 ，經過抗性篩選、分子量大小比較、雙酶切鑒定、和pcr鑒定等多種方法驗證，篩選出了5個陽性克隆。
  11. Tpt1 is essential for the vegetative growth of s. cerevisiae and codes for the trna 2 ' - phosphotransferase by using the plasmid shuffling technique, we have constructed a tpt1 - deleted strain and transformed it with trpt1 gene and found that the trpt1 could complement the yeast tpt1

    根據trpt1與模式生物酵母tpt1p的同源性，我們構建了tpt1的缺失菌株，利用plasmidshuffle技術，發現trpt1能夠互補酵母tpt1突變的功能，證明trpt1是tpt1的人類同源基因。
