  1. In meiosis it is not until anaphase ii that the centromere divides, the chromatids being termed daughter chromosomes after separation

    在減數分裂期間，直到分裂後期ii兩條染色單體才隨著著絲點的分裂而彼此分開。
  2. In the present paper, some investigations on loxoblemmus doenitzi ( gryllidae ) are reported. in order to discover the meiosis of spermatomeres and spermiogenesis, slice - pressing method and improved phenol - fuchsin dyeing method are used. in the course of meiosis, primary spermatocytes directly enter metaphase ii, not through telophase i and prophase ii

    本論文以直翅目、螽斯亞目、蟋蟀總科、蟋蟀科的多伊棺頭蟋（ loxoblemmusdoenitzi ）為材料，採用壓片法-改良苯酚品紅染色，研究了精子發生過程中的減數分裂階段和精子形成，發現初級精母細胞第一次減數分裂后不經過末期和前期直接進入中期。
  3. Oocyte maturation involves the activation of various signal trans - duction pathways that converge to activate maturation - promoting factor ( mpf ) ; this is a key activity that catalyses entry into m - phase of meiosis i and meiosis ii

    在爪蟾卵中有大量未被激活的cdc2 - cyclinb復合物，稱為pre - mpf ， pre - mpf在tyr15位脫磷酸變成活性mpf ，起到這個作用的磷酸酶是cdc25 ， cdc25的活性通過磷酸化和細胞位置進行調控。
  4. The expression of topoisomerase ii of cultured cells treated low dose ionizing radiation decreased and then returned as time went. and become outstanding as radiation dose and frequency were added. inhibitor of topoisomerase ii could cause chromosome non - dis juction in mitosis and meiosis. and the co - effect of inhibitor of topoisomerase ii and ion

    05 ） ，具有隨照射次數增加而增加的趨勢；小劑量電離輻射可以引起拓撲異構酶a表達變化，隨照射后時間延長先下降后回升，隨照射劑量和次數的增加，變化更加明顯；拓撲異構酶11a抑制劑可引起有絲分裂和減數分裂時染色體的不分離；拓撲異構酶a抑制劑和電高輻射的協同作用使染色體不分離更加明顯。
