dna modification 中文意思是什麼

dna modification 解釋
dna修飾作用,dna修飾
  • dna : 1. deoxyribonucleic acid 【生物化學】去[脫]氧核糖核酸。2. deoxypentose-nucleic acid 去[脫]氧戊糖核酸。
  • modification : n. 變更，更改，修正；改良，改進；緩和；修改；減輕；限制；【生物學】誘發變異，變態，變體，變型；【語法】修飾；（用變音符號的）母音改變。
  1. This fact suggested that dndb and dndc were directly involved in the novel dna modification in wild type s. lividans

    這兩個突變株均喪失了dnd表型，暗示這些基因與變鉛青鏈黴菌的異常修飾直接相關。
  2. These results indicate that the alteration of cell proliferation and dna synthesis caused by different gnt - v cdna transfection may at least partly result from the modification of n - glycan structure and function of egfr. it seems that the increased 1, 6 glcnac branch on the n - glycans of egfr may benefit to its binding with egf and the resulting tyrosine auto - phosphorylatio n, while the decrease of this branch may prevent these processes

    用特異性抗體結合westemblot結果發現，正義或反義gnt一vcdna的轉染並不引起pkb 、 p44 / 42mapk和mek蛋白質表達的變化，而gntv一s / h 」 21細胞pkbt308 、 5473位點磷酸化和免疫沉澱pkb的酪氨酸磷酸化以及以gsk召a /日磷酸化為指標的pkb的活性都較mock細胞增加， gntv一as / h7721細胞中這些指標的變化則相反。
  3. In this study, the suitable parameters for the introduction of plasmids phz1358 and pset152 into s. nanchangensis ns3226 from e. coli were tested for developing an conjugation system for s. nanchangensis ns3226. a dnd gene cluster, which encodes an unknown modification system for 5 hvidans 1326 and renders its dna susceptible to site - specific double - strand dna cleavage during electrophoresis was conjugated from e. coli into s. nanchangensis ns3226

    將克隆在整合型載體pset152上的變鉛青鏈黴菌1326的dnd基因簇通過接合轉移導入野生型南昌鏈黴菌ns3226中進行異源表達，觀察到接合轉移子的dna獲得了在含fe ~ （ 2 + ）的電泳緩沖液中電泳時降解的表型。
  4. Because there are many copies of chloroplast dna and the chloroplast has a strong tolerance to accumulation of the products expressed by the introduced foreign gene, a high level of expression is often happened in chloroplast transformation. in addition, because of prokaryotic property of the chloroplast, the prokaryotic gene can be expressed in chloroplast without any modification and multigene can be simultaneously transferred in " polycistron ", which is impossible in nucleic transformation

    另外，由於葉綠體基因組的原核性質，對來自原核生物的外源基因無需改造就可以在葉綠體內高效表達，而且可以將多個外源基因採取「多順反子」的原核表達形式同時引入，並由共同的啟動子控制，既方便操作又可避免由於存在多個相同啟動子所帶來的「共沉默」 。
  5. This unusual modification causes wild type s. lividans 1326 dna sensitive to site - specific oxidative double - strand cleavage ( dnd phenotype ). preliminary study revealed that such dna modification involves incorporation of sulphur. the entire functional dnd cluster, 8. 3kb in size, including 3 orfs - dnda, dndb and dndc was involved in this dna modification

    野生型變鉛青鏈黴菌具有一種不同於甲基化修飾的新型dna硫修飾系統，使dna在電泳時易遭到氧化雙鏈切割而導致降解（ dnd ， dnadegradation ）表型（ zhouetal . ， 1988 ， 1994 ， 1999 ） 。
  6. A novel dna modification discovered in streptomyces lividans is different from dna methylation. this unusual modification causes wild type s. lividans dna sensitive to site - specific oxidative double - strand cleavage ( dnd phenotype, dna degradation )

    變鉛青鏈黴菌的dna異常修飾系統是一種不同於甲基化修飾的新型修飾系統，它可使變鉛青鏈黴菌dna在電泳時易遭到氧化雙鏈切割（ dnd表型， dnadegradation ） （ zhouetal . ， 1988 ） 。
  7. He said this isa natural genedivergence 13 within the cat dna - one out of50, 000 cats will havethis divergence. so naturally divergent catswere found and thenbred so there is really no modification 14 ofthe gene. in the usalone 38 million households own a cat, andaround the world anestimated one in three humans suffer fromallergies. 1. allergic
