查询词典 ribosomes

Globin protein is synthesized by a set of 5 ribosomes attached to each mRNA.

Mitochondria was relatively little in size. Round primary lysosome with high electron-densed granules and secondary lysosome with high or low electron-densed granules were seen frequently. DCs contained many rough endoplasmic reticulum, the Golgi apparatus and ribosomes. The vacuoles with flocculent electron-densed granules were rare. Some special granules in cytoplasm were seen, whose surface like earphone were covered with a membrane. High electron-densed contents in the granules were near one side and the other side was bright. The nucleus became markedly small in volume, nephroid or hoofed in shape. The nucleus had little euchromatin and lots of heterochromatin under nuclear membrane.

子宫内膜癌组织DC超微结构特征如下：细胞形态不规则，与正常子宫内膜组织DC相比，胞膜较光滑，胞膜表面树突状胞浆突起显著减少，部分突起呈粗短状；胞质中线粒体相对少，圆形而电子密度高的初级溶酶体和不规则形且电子密度高低不一的次级溶酶体多见；高尔基体、粗面内质网、核糖体丰富；含微量絮状电子致密物的胞饮小泡显著减少；胞质中可见形态特殊的颗粒，该颗粒外周膜包裹，略呈圆形，中间部位稍弯曲，如耳机状，颗粒中由高电子致密物居于一侧，而另一侧则呈透亮状；胞核显著减小，居于胞质一侧，常呈肾形或马蹄形，核内常染色质较少，异染色质多边集于核膜下。

The studies on nucleolus focus on the sites of transcription and distribution of rDNA, assembly of ribosomes, and proteomics of nucleolus.

Pokeweed antiviral protein, a 29-kD protein isolated from Phytolacca americana, inhibits translation by catalytically removing a specific adenine residue from the large rRNA of the 60s subunit of eukaryotic ribosomes.

美洲商陆抗病毒蛋白(pokeweed antiviral proteins，PAPs)，是在美洲商陆的不同组织或不同生长阶段生成的一类具酶功能的单链核糖体失活蛋白(ribosome-inactivating proteins，RIP)，是天然的广谱抗病毒生物活性物资，能抗多种植物和动物病毒。

Some antibiotics work by gumming up the ribosomes of bacteria, allowing those bacteria to be stopped at no danger to their host.

有些工作脱胶了抗生素的细菌的核糖体，让这些细菌必须在不停止其主机的危险。

Nucleoli are the domains in which transcription and processing of rRNA and assembly of ribosomes take place.

16S rRNA plays an important role in the functional construction of ribosomes and is considered to be a conserved phylogenic marker of prokaryotic evolution.

16S rRNA对于构建功能性核糖体是十分重要的，人们普遍将其作为原核生物进化中保守的系统发育标志。
