  5. Alterations in dna methylation, an important regulator of gene transcription, lead to cancer

    對調節基因轉錄起重要作用的dna甲基化的異常將導致癌癥的發生。
  6. 2. low temperature, ga and 5 - azac all can decreased the methylation level of dna in plants

  7. The present paper studied the variation of dna methylation level in different developmental stage and different organs of non - heading chinese cabbage. germinated seeds and seedlings of non - heading chinese cabbage were treated with 5 - azacytidine ( 5 - azac ) ( demethylating agent ) combined with cold and gibberillin ( ga ). the assay analyzed the relationship between flowering and low temperature, ga and dna methylation and their interrelation

    本試驗採用去甲基劑5 -氮雜胞苷（ 5 - azac ）處理白菜的種子，並結合萌動種子和幼苗低溫處理及幼苗赤霉素（ ga ）處理，研究了低溫、赤霉素和dna甲基化與白菜開花及它們三者之間的關系，並測定了白菜不同生育期及不同組織器官核dna胞嘧啶甲基化水平的變化。
  8. 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 ） 。
  9. Dna methylation is atracting more and more attention in the research of tumor and its diagnosis and cure

    Dna甲基化在腫瘤發生發展機制的研究及腫瘤的診斷與治療中越來越受到重視。
  10. " this suggests that the presence of dna methylation in normal tissue adjacent to tumors is more prealent that preiously thought.

    「這表明瘤旁組織的dna甲基化比我們原先想的要普遍。 」
  11. At the launch of the epigenome project on tuesday, the group also released the results of a large pilot project that give " definitive proof " that dna methylation patterns are tissue specific, says beck

    甲基化是主要發生在在胞嘧啶（組成dna的四個基或字母之）的一個自然過程.當一個甲基群被加到一個基因的促進者區域（ -引發基因被表現的系列- ）的胞嘧啶上時基因就被關閉了。
  12. Research in recent years showed that dna methylation play a role in regulating gene expression, but the assay on relationship between dna methylation and flowering were mainly focused on model plants such as arabidopsis

    近年來的研究表明， dna甲基化在植物基因表達調控中發揮重要的作用，但有關甲基化與植物開花關系的研究只是在擬南芥等模式植物上進行的較多，其它植物上的報道還很少。
  13. In addition, molecular experiments indicated that resistance was not relevant to copy number or to insertion sites, but instead to the repeated gfp structure and to methylation of genomic dna. pvx vectors were constructed that contained the s6 gene of rbsdv vi and the 14 kd fragment of bnyvv rna2

    分子檢測結果顯示， gfp3植株中普遍存在gfp基因的沉默現象，且gfpdna的甲基化程度明顯高於gfp1植株，說明這些植株對于病毒的抗性與目的基因的插入位點及拷貝數和無關，但與串聯重復的gfp基因結構形式密切相關。
