著絲粒區 的英文怎麼說
中文拼音 [zhāosīlìqū]
著絲粒區
英文
kinetochore domain-
The duplicates are attached to each other at a constricted region called the centromere.
對偶體彼此相連于稱為著絲粒的縮小的區域。The centromere is a specific genetic locus and remains relatively uncoiled during prophase, appearing as a primary constriction
著絲粒是一個特化的遺傳區域，在細胞分裂的早期始終保持解開的結構，所以也叫做主縊痕。In normal greenhouse condition, coda - transgenic wheat lines ( to ) had the same plant morphorlogy and pollen i2 - ki staining rate as untransformed control plant. after treating with 300 mm of 5 - fc, however, changes in configurations of spikelet, floret and anther have been observed in the transgenic lines but not in the control, and 50 % gus - positive lines displayed outside - opened glume, abnormal stamen, smaller and thinner anther, shorter filament, and failure of selfing. in parts of 5 - fc - treated transgenic lines, the pollen staining rate by i2 - ki was much lower than that of untransformed control
溫室栽培的轉基因小麥苗（ t _ 0 ）未噴5 - fc處理時植株外部形態和花粉碘-碘化鉀染色的著色率與未轉基因的對照沒有差異；用300mm的5 - fc處理后，發現有50 gus陽性株系與對照有明顯的區別，表現為小穗穎殼外張，花絲短縮，花藥發育不良，較小、黃白色且花粉粒少，自花不授粉，無外來花粉授粉則不結實。Centromere the region of the chromosome that contains the kinetochore, the structure that becomes attached to the nuclear spindle during mitosis and meiosis
著絲粒：染色體上包含著絲點的區域，在細胞有絲分裂和減數分裂期間與紡錘體相整合的一種結構。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
我們通過pcr和序列分析，選擇了含有擬南芥著絲粒區178bp串連重復序列的yac克隆作為構建人工染色體的基礎，同時也克隆了擬南芥的端粒和ars等序列。分享友人
