查询词典 nuclear division

Amitosis Nuclear division characterized by the absence of a nuclear spindle and leading to the production of daughter nuclei with unequal sets of chromosomes.

无丝分裂：是一种比较简单的分裂方式。

The number of nuclei in synchronous blastoderm is much fewer than that in wild type group, and the distribution of nuclei was uneven, which indicates that the nuclear division in mutated early embryos was asynchronous and maybe some nuclei undergoes degeneration.

推测HIRA可能影响了染色体的结构和组装，从而影响了细胞周期的进程，导致果蝇早期胚胎细胞核分裂异不正常。

Due to the deficiency of cyclin B1 and 〓, spermatogonia and pachytene/diplotene primary spermatocytes in contralateral cryptorchid testis were unable to form MPF, and therefore, they could not accomplish their nuclear division, and became arrested at the transition stage from mitosis to meiosis (G2/M phase). We also found that testosterone could regulate the cyclin B1 expression in spermatogenic cells.

由于cyclin B1和〓的缺失，粗线期/双线期初级精母细胞中的MPF无望形成，从而导致生精细胞分裂停滞在由有丝分裂向减数分裂过渡的G2/M相；（5）睾酮可在翻译水平上调控阴囊内睾丸生精细胞cyclin B1蛋白的表达。

Cytokinesis The division of the cytoplasm after nuclear division.

胞质分裂：随着核分裂之后的细胞质的分裂。

Euchromatin stains more intensively than heterochromatin during nuclear division.

常染色质具有转录活性，因而可以进行蛋白质的合成，而异染色质通常不具有转录活性。

The centromere contains the kinetochore, a structure involved in the attachment of the chromosomes to the spindle during nuclear division.

Figure8 10×40The epicyte colouration of the tumor cell is positive to CD21, and performs nuclear division, but the lymphocyte and acidophic cell is negtive.

图8 10×40 CD21胞膜染色阳性，可见核分裂相，而淋巴细胞及嗜酸性细胞阴性

It was showed that throughout the nuclear division, nuclear membrane did not disintegrate,lamina always existed; But only one lamin peptide (similar to lamin B in higher eukaryotes) was expressed during division,ant its expression quantity changed according to the progress of division: in interphase, lamin was constant; when entering G1 phase, lamin increased sharply; then, increased slowly untill division finished.

结果表明：在整个核分裂过程中，核膜不崩解，核纤层结构一直存在；但随着分裂的进展，始终只有一种成分（类似于高等生物lamin B ）的表达；其表达量随着分裂时相的推移而变化：间期时，比较恒定，进入G1期时明显增加；以后不断略有增加，直到分裂完成。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
