Transcript-selective translational control of eukaryotic gene expression is often directed by structural elements in the 5' and 3' untranslated region (5' and 3' UTR) of the mRNA.

在真核细胞中，基因的表现若是藉由调控转译的进行，通常是藉由 mRNA的 5'或3'端非转译区域上的二级结构的参与。

This result suggested that the regulation region could exist in the 5′untranslated region of EG Ⅲ mRNA, which is recognized by the gene expression related factors of S. cerevisiae.

这表明瑞氏木霉的EG Ⅲ基因在酿酒酵母细胞中表达时，其mRNA 5'端先导序列中可能存在影响该基因翻译水平的调控序列。

The plasmid of pEGFP-N1 was preserved in our laboratory.②The rat vibrissa follicles were dissected under a stereomicroscope. The dermal sheath was moved by incubated in dispase. The bulge regions of the hair follicles in anagen phase were carefully cut between the arrector pili muscle and the sebaceous gland, and then incubated with a mixture of trypsin and EDTA. The cell suspension was selected, and cultured in 10% fetal bovine serum DMEM/F12 FAD medium. After 7 days culture, HFSC was obtained by rapid adhering on collagen Ⅳ.

实验方法：大鼠在体视显微镜下分离出含真皮鞘的完整毛囊，dispase消化，将毛囊从真皮鞘中挤出，收集形态完好且处于生长期的毛囊，分别在毛球部上端、皮脂腺下端横切毛囊，取中间部分置于胰酶和EDTA中联合消化，向所得细胞悬液中添加含10%胎牛血清DMEM/F12完全FAD培养基，常规培养7 d后，采用IV型胶原快速贴壁法两次筛选以分离纯化大鼠毛囊干细胞。

In general,ameloblastic carcinoma is ahighly aggressive tumor with rapid growth,and cases of distant metastasis had been reported.

一般认为，造釉细胞癌是生长快速并具有高度侵犯性的肿瘤，亦曾有发生远端转移的病例被报导。

It is the first time that these phenomena were observed: Two nuclei are surrounded by plasma and locate at the central of the female gametophyte and the others nuclei are positioned at the fringe of the female gametophyte; Before the pollen tube enters the female gametophyte. the nuclei in chalazal end begin splitting of plasma and form multinuclear cell.4. The pollens of Gnetumc are spherical or applanate with single aperture. The ornamentation of exine is spine. The basis part of spine is lenience and the top part of spine is tip or obtuse sphere.

首次在买麻藤属植物的雌配子体中观察到2个游离核位于配子体的中央位置，且被一团原生质所包围的，其余的游离核位于边缘的现象以及花粉管进入雌配子体前，合点端的核已经发生胞质分裂形成多核细胞的现象 4、买麻藤的花粉近球形或扁平型，有单萌发孔，外壁表面具小刺状纹饰，小刺基部宽大，末端尖或钝圆。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
