chromatids 中文意思是什麼

chromatids 解釋
染色單體
  1. During mitosis, sister chromatids remain joined by their centromere until anaphase

    在有絲分裂期間，姐妹染色單體在分裂後期之前都是通過著絲點連接的。
  2. Anaphase the stage in mitosis or meiosis when chromatids are pulled toward opposite poles of the nuclear spindle

    後期:在有絲分裂或者減數分裂過程中染色單體分別朝相反的兩極運動。
  3. During anaphase i of meiosis pairs of chromatids still connected at their centromere move to the spindle poles

    在減數分裂後期i中，由於紡錘絲的牽引，使成對的同源染色體各自發生分離，並分別向兩極移動。
  4. 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。
  5. Each chromosome consists of two chromatids held together by the centromere.

    每個染色體由兩個染色單體所組成，它們被一個著絲點聯結在一起。
  6. Following the replication of chromosomes, resultant chromatids remain attached at the centromere

    隨著染色體的復制，著絲粒始終連接著形成的兩個染色單體。
  7. During anaphase ii the centromeres divide and single chromatids are drawn toward the poles, thus sister chromatids are separated

    在減數分裂後期ii ，每條染色體的兩個染色單體隨著著絲點的分裂而彼此分開，由紡錘絲牽向兩極。
  8. 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。
  9. During diakinesis the sister chromatids of homologous pairs of chromosomes complete their separation, and the chromosomes coil tightly, shortening and thickening

    在終變期配對的同源染色體中的姐妹染色單體完成分離，染色體變成緊密凝集的狀態，縮至最小長度。
  10. Alternatively, like allopolyploids, they may arise by the nondisjunction of chromatids during the mitotic division of a zygote

    與異源多倍體相似的是，它們也是在有絲分裂中合子的染色單體不分離形成的。
  11. At this point esch chromosome consist of a pair of chromatids and the two associated chromosomes are termed a tetrad

    此時每條染色體由一對染色單體構成，這兩條聯合的染色體稱為四分體。
  12. In meiosis, the association of four homologous chromatids seen during the pachytene stage of prophase

    減數分裂前期的粗線期中，四個同源的染色單體向聯系形成的結構。
