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

著絲粒指數的求解依賴于著絲粒定位和染色體長度。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。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。Chromomere a small beadlike deeply staining structure seen in chromosomes during prophase of mitosis and meiosis
染色粒:在有絲分裂及減數分裂的前期存在於染色體上的小念珠狀的著色深的結構。( 3 ) the chromosomes obtained by air - drying and chromosomes from the silkworm genital gland are similar in shape. but the numbers and the length of the chromosomes are obviously different. the chromosomes obtained from the genital gland have little difference in length, while the chromosomes of bmn cell are different in length very much
但是,在染色體的數目上有顯著的差異。另外,染色體間的長短差別也非常明顯。由家蠶生殖腺得到的減數分裂中期染色體和胚胎得到有絲分裂的中期染色體,其染色體長短差異不明顯,而binn細胞的中期染色體長短非常不一致,差異非常顯著。Application of chitosan in dyeing of tussah silk
殼聚糖在柞絲綢染色中的應用The reasults are summed up as following : ( 1 ) the more metaphase chromosomes of bmn cells and moderately contraction can be obtained by air - drying after cultured at the colchicine concentration 1. 0 u g / ml, 28 " c, for 6 - 9h
用空氣乾燥法和培養細胞貼片法對bmn細胞的染色體和有絲分裂進行研究發現: ( 1 )採用空氣乾燥法制備bmn細胞的染色體,在終濃度0 . 1ug / ml的秋水仙素28培養6 9h條件下可得到較多中期分裂相,染色體的凝集也比較適中。It is likely that telocentric chromosomes with minute sizes may be ancestral types of the vertebrate chromosomes. 2
從文昌魚染色體的核型看,似乎形態較小的端部著絲粒染色體是脊椎動物染色體的遠祖。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。After the processing of chromosome image, using then method of tab, we can finish automatic division of chromosome image and get the single chromosomes. in the automatic processing of chromosome division, we can erase impurity and save chromosomes that we will need to label in the end. area, girth, centromer index are important features in identifying the chromosomes
對染色體圖像進行處理以後,利用標號法實現了染色體圖像的自動分割,得到單條染色體圖像,在染色體的自動分割提取的過程中,可以對雜質實行去除,而保留我們需要用來進行識別的染色體,面積,周長,著絲粒指數是識別染色體的重要特徵。The experiment results indicate this method is good, we select area, girth. centromer index to classify the chromosomes
實驗證明這種方法是有效的,我們提取並選擇染色體的面積,周長,著絲粒指數作為以後分類的依據。Because of its fully sequenced genome and the most complete, contiguous nucleotide sequence of centromeric dna in plants, arabidopsis was chose as the base to construct plant artificial chromosome. we identified two candidate yac clones, cic8h8 and cic6f6, which are both proved to have the 178 bp arabidopsis centromeric repeat sequences
