nuclear spindle 中文意思是什麼
nuclear spindle
解釋
核紡錘體-
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。 -
As the cyclin dependent kinase, cdc2 may act at multiple levels during mitosis to repress ribosome biogenesis, which lead the biosynthesis to a relative silent phase, when the most of cell ' s energy expenditure is used in chromosome condensation, breakdown of the nuclear envelope, and formation of the mitotic spindle
作為cyclin依賴激酶， cdc2的激酶活性在很大程度上抑制了細胞的合成代謝，使細胞的蛋白合成進入了一個相對的靜止期，而細胞主要的能量則被應用於細胞分裂時的染色體的濃縮、核膜的降解、紡錘體的形成等。 -
Oleifera was observed with lm. results showed that there were vegetative cell and generative cell in the pollen grain of genus camellia, the generative cell is more smaller than that of the vegetative cell. the generative cell was lay on the vegetative cell as an elongate spindle, and only the generative cell membrane and nuclear membrane which near the cell polar linked up the vegetative cell membrane, one of the linked area was located near by the aperture of pollen grain
結果表明，山茶屬植物花粉粒中含有生殖細胞和營養細胞，生殖細胞較小，呈長紡錘形，游離在營養細胞中，生殖細胞極軸兩端的細胞膜和核膜與營養細胞的細胞膜相連，其中一端的連結處位於花粉粒萌發孔附近。 -
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。
