细胞分裂

Department of Microbiology and Immunology is primarily dedicated to teaching and research in protein secretion in Escherichia coli, cell wall synthesis and cell division in Escherichia coli, interactions and functions of proteins, mechanism of DNA replication arrest, microbial pathogenesis, microbial genetics, immunodeficiency, immunogenetics, infectious diseases, molecular biology, etc.

微生物学与免疫学系主要致力于微生物学与免疫学的教学与研究，其研究领域包括大肠杆菌的蛋白质分泌，大肠杆菌细胞壁合成和细胞分裂，蛋白质的相互作用和功能，DNA 复制抑制机理，微生物致病机理，微生物遗传学，免疫缺陷，遗传学，传染病，分子生物学等。

Objective:To improve the detecting resolution of genes on interphase cells for assisting in clinical diagnosis.

目的为了提高细胞分裂间期细胞核基因检测的分辨率，以协助临床诊断。

During cell division,chromosome segregation is governed by the interaction of spindle microtubules with the kinetochore.

细胞分裂时，染色体的分离由纺锤体微管协同动点完成。从纺锤体两极发出的极间微管发生重排，在分开移向两极的染色单体之间形成严密整齐的动态结构：中心纺锤体。

Mature embryo sac can form from megaspore mother cell on the modified VW medium supplemented with 0.5mg/L BA and 0.1 mg/L NAA.

在培养基无外源激素或仅含生长素或细胞分裂素时，雌配子体的发生过程不能顺利完成；在改良VW培养基上添加0.5 mg/L BA和0.1 mg/LNAA时，形成成熟胚囊。

The results showed this gene is overexpressed in genetic tumor and meristem tissues, suggesting that this gene is closely related to cell division and tumor formation in plant.

Northern杂交结果表明，此周期蛋白基因在遗传瘤及顶端分生组织中高表达，说明这个基因与遗传瘤的形成及细胞分裂联系密切。

The zygote, by cell division, grows into a morula an then into a blastocyst.

通过细胞分裂，受精卵发育成桑葚胚，然后发育成囊胚。

Morula in the uterine cavity to continue cell division to form the blastocyst, about 6-8 days after fertilization into the endometrium, a process known as implantation or cultivation.

桑椹胚在子宫腔内继续细胞分裂形成胚泡，大约在受精后6—8天进入子宫内膜，这个过程叫做着床或种植。

Under normal physiological conditions IGF-1 enhances DNA and protein synthesis in cardiomyocytes, it promotes myofibril development, and it is necessary for entry into the S-phase of the cell cycle.

在正常的生理条件下，IGF-1能够提高cardiomyocytes 中的DNA和蛋白质的合成，它促进了肌纤维的发展，这个是细胞分裂周期中进入S期的必要条件。

Because 3 months less than has breed,this is fetal the capacity that still does not have synthetic interferon, boycott the infection of nettle rash virus hard, virus of measles of as a result breeds in great quantities, block sluggish segmentation, the become divided of cloggy organization, form deformation thereby, if harelipped, palate is raided, small head, cataract, congenital obstacle of growth of deaf-mute, bone.

这是因为孕育3个月以内有胎儿尚不具备合成干扰素的能力，难以抵制风疹病毒的感染，以致风疹病毒大量繁殖，阻滞细胞分裂，妨碍组织的分化，从而形成畸形，如兔唇、腭袭、小头、白内障、先天性聋哑、骨发育障碍等。

The ovule of development is the one nucellus that make a group at first organization, because basilar segmentation is rapidder and form or two bags by the layer, bead by , other nucellus the organization laps inside and next alveolus stays in one aspect of the matter, bead aperture .

发育的胚珠最初是一整团珠心组织，由于基部的细胞分裂较快而形成一层或两层包被层—珠被，将其他珠心组织包裹在内并在一端留下一个小孔—珠孔。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
