原核细胞rRNA有三种16S23S和5SrRNA overview •细胞中,由RNA聚合酶合成的RNA为初级转录产物,一般需要加工,才能成为成熟的RNA,体现相应功能。•真核细胞的几乎所有的初级转录产物均要经过加工才能成熟;原核细胞的tRNA和rRNA的初级转录产物,需要加工才能成 熟;而原核细胞的mRNA的初级转录产物,无需加工就可作...
The 5S coding region was 100% identical to the directly sequenced 5S rRNA from Ginkgo (GenBank M10433.1 from Hori et al., 1985) indicating that we cloned an apparently functional gene that is likely to be expressed. On the other hand, there were two mutations in the 5S coding region of...
5S rRNA存在于所有物种的细胞质核糖体中,5S rRNA非常小,其长度在100-200 nt之间。但是其二级结构却在所有物种中都高度保守。其二级结构包括5个螺旋(I-V)和5个环(A-E)。 5S rRNA及其相互作用的蛋白可以形成一个叫中央凸起(central protuberance)的结构,毗邻两大活性中心GTPase关联中心(GAC)和肽基转移酶中心(PTC...
