核糖体

Ribosomes are responsible for the synthesis of polypeptide chains and its biogenesis is thus a critical process inextricably linked to cell growth and proliferation.

核糖体负责细胞内蛋白质的合成，其数量和状态跟细胞的生长密切相关。

Recently, a small RIP named as cinphorin was isolated from the seed of camphor tree.

最近，从香樟种子中还分离到另一种微型双链核糖体失活蛋白，命名为新丰毒蛋白。

It was concluded that the split of the interchain disulfide bond of type Ⅱ RIPs was the first step for the catabolism in their respective cells.

这些实验结果为了解Ⅱ型核糖体失活蛋白在植物细胞内的降解代谢途径提供了一个新的思路。

Results showed that specific SIEA26~28 ku scFv with high level expression was achieved. The corresponding gene, ribosomal protein S4 was obtained by initially screening the cercaria cDNA library with the specific SIEA26~28 ku scFv. The obtaining of specific SIEA26~28 ku scFv lays the foundation for further screening and identification of the coding genes of SIEA26~28 ku, the natural molecular candidate vaccine against schistosomiasis.

结果显示，所获得的SIEA26~28ku特异性scFv，表达量高，采用该探针初步筛选出相关基因核糖体蛋白S4SIEA26~28ku特异性scFv的获得，为进一步筛选、分析鉴定抗日本血吸虫病天然分子候选疫苗SIEA26~28ku的编码基因奠定了基础。

We now know that chloramphenicol specifically affects the ribosomes of prokaryotic cells, thus inhibiting protein synthesis.

现在我们知道抗生素对原核生物细胞中的核糖体有特殊效应，从而能抑制其蛋白质的合成。

It is clear from the comparison of the number of AmphiL34 and AmphiS29 genes with that of rat L34 and S29 genes that duplication of L34 and S29 genes occurred in vertebrates like rat. It therefore appears that the housekeeping ribosomal proteins genes such as L34 and S29 also underwent large-scale duplication during the early chordate evolution.

这一结果分别与大鼠7-9个L34拷贝数和14-17个S29拷贝数相比较，证明持家核糖体蛋白基因L34和S29基因在脊椎动物起源与进化过程中发生了大规模扩增，符合两轮基因倍增规律。

Based on macromorphological and micromorphological characters, as well as conidium ornamentation observed with scanning electron microscopy, Aspergillus sp. D-l was affiliated to Aspergillus Section Versicolores. Further, DNA sequence of the internal transcribed spacer was used as the molecular characteristic, and analyzed with the DNAMAN 5.2.2 program and the Mega 3.0 program.

采用真菌核糖体基因内转录间隔区序列作为分子标记，利用DNAMAN 5.2.2和Mega 3.0等软件对其进行同源性和进化关系分析，在种的水平上将Aspergillus sp.D-1归属为Aspergillus versicolor，并将该菌株命名为A.versicolor D-1。

Ribosomes are found in large numbers in all cells, free in the cytoplasm or bound to endoplasmic reticulum.

核糖体在很多的细胞中大量的存在，在细胞质中自由存在，或与内质网结合在一起。

To study the sedimentation coefficient of ribosomal RNA from Saccharomyces cerevisiae,the enzymolysis method and the liquid nitrogen grounding method combined with Trizol Reagent were used for total RNA extraction from Saccharomyces cerevisiae.RNA extraction in Mus musculus Kunming and Danio rerio,was also involved in,which was set as control.

为研究酿酒酵母菌核糖体RNA的沉降系数，用酶解法和液氮研磨法裂解酿酒酵母菌的细胞壁，Trizol Reagent提取其总RNA，同时提取小白鼠和斑马鱼的总RNA进行比较。

Fig 1 Normal hepatocyte:glycogen particles aggregated,mitochondrialcristae clear,endoplasmic reticulum abundant ×10500;and no Ce-H2O2 precipitation ×10 500;Fig 3 1 h after Cd-injection:ER dilatant,ribosomes mostly dislodged,mitochondria slightly swollen,small amount of Ce-H2O2 precipitation

图1 正常肝细胞：糖原颗粒聚集，粗面内质网丰富，线粒体嵴清晰×10 500；图2 染镉后30分钟：肝细胞结构正常，未见Ce的沉积×10 500；图3 染镉后1小时：ER扩张，核糖体已大部脱落，线粒体轻度肿胀；可见少量

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
