核紡錘體 的英文怎麼說
中文拼音 [hébǎngchuítǐ]
核紡錘體
英文
nuclear spindle-
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。After the treatment was removed for 6 min, the nucleus began to reform in those eggs that the spindle did not recover. after 9 min, new nuclei had been reformed completely. the activated eggs entered the prophase of the next cleavage cycle in about 14 min, the metaphase in 19min ; the anaphase in 24min and the telophase in 29min
未恢復紡錘體的激活卵在解除休克后6min ，卵內染色體開始核化， 9min時形成新的二倍體細胞核， 14min時處入再次分裂的前期， 19min時進入分裂中期， 24min進入分裂後期， 29min時處于分裂末期，且可以看到子核的形成。Since the success of dolly, the first cloned sheep with the adult somatic cells as karyoplast donor, new approaches have been developed for nuclear transfer technology. here we describe a handmade cloning method which combines the chemical induced enuleation and zona - free technology in embryo culture. enuleated oocytes were derived by exposing the oocytes to demecolcine and cytoheximide supplemented mdium sequently and its chromosome was depleted to the first polar body
將培養10h的化學去核卵母細胞與供體成纖維細胞融合后lh 、 2h 、 3h ，分別有77 . 6 % 、 70 . 6 % 、 58 . 9 %重構胚的染色質發生凝集，其餘胚胎的染色體則處于原核期;而只在融合后3h ， 27 . 9 %重構胚被標記出組裝的紡錘體，且其中的同源染色體己經分離。Effects of mouse oocyte ages on spindles location and enucleation efficiency
