| 1. | The nucleoplasm is surrounded by the nuclear envelope .
核质被核膜包裹。 |
| 2. | In human epithelial cells, sex chromatin appears as a small granule attached to the nuclear envelope .
在人的上皮细胞中，性染色质象个小颗粒，连在核膜上。 |
| 3. | Nuclear envelope and lamins
核被和核纤层蛋白 |
| 4. | During the period of provitellogenic oocytes , the nucleoli migrate to the inside of nuclear envelope , and the matter in the nucleus enters cytoplasm through nuclear pore
卵黄形成前的卵母细胞期，卵母细胞核仁移到核膜内侧，核内物质通过核孔进入细胞质。 |
| 5. | Endoplasmic reticulum ( er ) a system of membranes forming tubular channels and flattened sacs ( cisternae ) , running through the cytoplasm of all eukaryotic cells and continuous with the nuclear envelope
内质网：是真核细胞细胞质内的一种管道或扁平囊状的膜系统，与核膜相连。 |
| 6. | Within 2h isolation from the follicle 100 % of oocytes underwent germinal vesicle breakdown and both the nucleolus and the nuclear envelope disappeared . after culturing for 6 h , prometaphase occurred in 90 % oocytes
本研究旨在探索一种崭新的、化学试剂诱导去核卵母细胞为核受体的、无透明带的、手工体细胞核移植方法。 |
| 7. | 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
作为cyclin依赖激酶， cdc2的激酶活性在很大程度上抑制了细胞的合成代谢，使细胞的蛋白合成进入了一个相对的静止期，而细胞主要的能量则被应用于细胞分裂时的染色体的浓缩、核膜的降解、纺锤体的形成等。 |
| 8. | It was also found that the nuclear envelope disappeared earlier at the micropylar end than that at the chalazal end . the speed of the programmed cell death were different in three nonfunctional megaspores at the micropylar end and their relationships with the neighboring cells were also different . the biological significance was discussed about these phenomenon
还发现了大孢子母细胞合点端的核膜先于珠孔端的消失，并且珠孔端3个大孢子的死亡时间不同，与相邻细胞的关系也不同，进而讨论了这些现象的生物学意义。 |
