  1. In addition to avermectins, s. avermitilis produces oligomycin, a strongly toxic compound. gene deletion vector pxl05 was used to disrupt oligomycin polyketide synthase ( pks ) encoding genes ( olma ) in streptomyces avermitilis cz8 - 73, the producer of anthelmintic avermectins b and the cell growth inhibitor oligomycin. olma gene cluster in the chromosome was displaced by deletion allele on the plasmid via double crossover

    本研究以產阿維菌素b和寡黴素的阿維鏈黴菌cz8 - 73為出發菌株，構建了基因缺失載體pxl05 ，並將其轉入cz8 - 73中，通過缺失載體和染色體之間的同源雙交換，對染色體上長達90kb的寡黴素聚酮合酶（ pks ）基因簇（ olma ）進行了缺失。
  2. Crossing over the exchange of material between homologous chromatids by the formation of chiasmata

    交換：同源染色單體之間形成交叉時遺傳物質的交換現象。
  3. Asymmetrical chromatid exchange

    非對稱型染色單體交換
  4. However, when spermand egg cells are formed, the maternal and paternal chromosomes swap bits ofdna to create a new mixture

    然而，當精子和卵子形成時，父系和母系的染色體都會交換若干dna ，生成新的混合體。
  5. Cross-overs have occurred independently of each other between pair of homologous chromosomes.

    交換現象獨立地在每一對同源染色體之間發生。
  6. Several studies have shown that so2 and its derivatives could induce chromosomal aberrations, sister chromatid exchanges and micronuclei in human blood lymphocyte, bone marrow cell in mice and chl

    研究發現， so _ 2及其衍生物可引起人外周血淋巴細胞、小鼠骨髓細胞、中國倉鼠肺成纖維細胞等哺乳動物細胞的染色體畸變、姊妹染色單體交換及微核的形成。
  7. Linkage analysis plays an important role in gene mapping. the foundation : the two gene locuses which locate on the same chromosomal ( eg. disease gene and marker gene ) happen to cross over and recombine. the farther the distance between two locuses is, the higher the probability happening to cross over is, the lower the probability that the two locuses are inherited to offspring together is, that is, the degree of linkage is not strong. so we can estimate the distance and the degree of linkage by the recombination fraction between the two locuses to locate gene

    連鎖分析是基因定位主要策略之一，其基本原理是位於同一染色體上兩個基因位點（例致病基因與標記基因）在減數分裂的過程中會發生交換與重組，染色體上的兩個位點間距離越遠，發生重組的概率就越大，兩個位點在一起傳給後代的機會就越少，即連鎖程度弱，這樣由標記位點與疾病位點間的重組率可估算出兩者間的距離以及連鎖程度，達到基因定位的目的。
  8. Al toxicity - induced ultraweak luminescence ( ul ), sister - chromatid exchanges ( sces ), programmed cell death ( pcd ) in root tips of barley, al - resistant genetic engineering and the role of root border cells in al toxicity were studied respectively, in order to explore some new pathways for al toxicity, al - resistant mechanism and genetic improvement

    大麥是鋁毒極為敏感的作物，本實驗以大麥為材料，開展了鋁毒誘導的根尖細胞超微弱發光、姐妹染色單體交換（ sce ） 、細胞程序性死亡、耐鋁基因工程及邊緣細胞在鋁毒中的功能研究。試圖為植物鋁毒及耐鋁機制和遺傳改良研究探索新途徑。
  9. The simple genetic algorithms, based on the darwinism of the survival of fittest by darwin, map the searched space as the genetic space. each solution is coded as a vector, called a chromosome or an individual, denoted as a bit strand. the global optimum result is obtained by the selection, variation and change of the bits

    基本遺傳演算法是基於達爾文的物競天擇、優勝劣汰、適者生存的自然選擇和自然遺傳機理，把搜索空間映射為遺傳空間，即把每一個可能的解編碼為一個向量，稱為一個染色體或個體，它表示為二進制串，再通過選擇、變異、交換操作達到全局最優的目的。
  10. The deletion mutants were proved to be genetically stable, and thus might be promising strains in industrial production of avermectins b. although s. avermitilis produces eight related components of avermectins, only two components, bla and bib, are available for the medical, veterinary and agricultural fields

    該缺失突變是在染色體上通過同源雙交換完成的，不會發生進一步的重組，因此突變株性狀穩定，在工業生產上具有應用價值。阿維菌素的天然發酵產物共有八個組分，其中只有b1組分的殺蟲活性最高，被作為殺蟲劑在農業和畜牧業中使用。
