  1. Standard guide for determining dna single - strand damage in eukaryotic cells using the comet assay

    用彗星分析法測定真核細胞中dna單線損傷的標準指南
  2. In e coli, dna polymerases are key enzymes involved in two distinguished pathways contributing to untargeted mutagenesis. replication of dna by pol v ( umuc ), in the presence of umud1, reca and single strand binding protein ( ssb ), is highly mutagenic and exhibits a predominant mutation pattern of base transversion. another error prone polymerase involved in untargeted mutagenesis is pol iv, encoded by dinb gene

    在umud ' ， reca和單鏈結合蛋白ssb的協助下， polv （ umuc ）能在單鏈模板上催化dna合成並產生高頻率的以堿基顛換為主要形式的突變；另一個與非定標性突變有關的易誤dna聚合酶是pol ，為dinb基因的編碼產物。
  3. The dissertation consists of five chapters : in chapter one, the recent progress in molecular approaches in systematic studies of macroalgae e. g. dna extraction, restriction endonuclease fragment length polymorphisms ( rflps ), random amplified polymorphic dna ( rapd ), gene sequencing, intersimple sequence jepeats ( issr ), amplified fragment length polymorphisms ( aflp ) and single strand. conformation polymorphisms ( sscp ) were reviewed

    本論文由五部分組成：在第一部分，綜述了大型海藻dna的提取、限制性片段長度多態性（ rflps ） 、隨機擴增多態性dna （ rapd ） 、核酸序列分析、擴增片段長度多態（ aflp ） 、單鏈構象多態（ sscp ）等分子手段在大型海藻系統學研究中應用的一些進展。
  4. Up to the mid - 1970s, it was thought that a gene was one single continuous segment of the dna strand - until it was discovered that in higher organisms such as ourselves a gene can consist of several different segments that have to splice themselves together like pieces of edited movie film before they can pass on their information in the growth of new cells

    一九七零年代中以前，世人以為基因是一個完整而無間斷的dna片段；但后來發現，人類及其他高等生物的基因由幾個片段構成，要像剪接電影一樣併合起來，才能在新細胞生長過程中傳遞訊息。
  5. The results showed that : significant increase in dna migration and comet frequency in the spleen, thymus, bone marrow and peripheral lymphocytes were induced after intraperitoneal treatment of mtx at a dose of 1. 25 ~ 5mg / kg. no obvious increase in dna single strand breaks was observed in the liver, kidney, testicle and stomach of the mice with the same treatment. the migration of nuclear dna and comet frequency of spleen, thymus, bone marrow and peripheral lymphocytes in the dose - response study showed a dose - dependent increase

    實驗結果：腹腔注射5mg kgmtx后3h可誘發小鼠體內脾細胞、骨髓細胞、胸腺細胞和外周血淋巴細胞的dna單鏈斷裂且隨時間延長損傷程度增大，於12h達到高峰，但未觀察到對肝、腎、胃和睪丸細胞的山窗民科大學碩士學位論文影響;核dna損傷程度隨著用藥劑量的增大而增大。
  6. Experiment about single - strand dna breaks in permanent middle cerebral artery occlusion of rats

    單鏈斷裂損傷的實驗研究
  7. Numerous lesions that include sugar alteration, base damage, and single - and double - strand breaks together with dna - dna crosslinks have been identified in irradiated dna. dna double strand breaks ( dsbs ) are considered as the most important initial damage of all biological effects induced by ionizing radiation

    電離輻射可引起dna多種類型的損傷，如堿基損傷、糖基損傷、單鏈和雙鏈斷裂以及dna交聯等，其中雙鏈斷裂（ dsb ）是輻射所致生物效應中最重要的原初損傷。
