核糖体,旧称“核糖核蛋白体”或“核蛋白体”,是细胞中的一种细胞器,由一大一小两个次单元结合形成,主要成分是相互缠绕的RNA(称为“核糖体RNA”,ribosomal RNA,简称“rRNA”)和蛋白质(称为“核糖体蛋白质”,ribosomal protein,简称“RP”)。核糖体是细胞内蛋白质合成的场所,能读取信使RNA核苷酸串行所包含的遗传信息,并使之转化为蛋白质中氨基酸的串行信息以合成蛋白质。在原核生物及真核生物(地球上的两种具有细胞结构的主要生命形式,前者可细分为古菌、真细菌两类)的细胞中都有核糖体存在。一般而言,原核细胞只有一种核糖体,而真核细胞具有两种核糖体(其中线粒体和叶绿体中的核糖体与细胞质核糖体不相同)。

Ribosome 核糖体

   Figure 1 : The ribosome assembles polymeric protein molecules whose sequence is controlled by the sequence of messenger RNA molecules. This is required by all living cells and associated viruses.
Figure 2 : Large (red) and small (blue) subunit fit together.
Figure 3 : Atomic structure of the 30S Subunit from Thermus thermophilus.[8] Proteins are shown in blue and the single RNA chain in orange.

The ribosome (/ˈrbəˌsm, -b-/) is a complex molecular machine found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules. Ribosomes consist of two major components: the small ribosomal subunit, which reads the RNA, and the large subunit, which joins amino acids to form a polypeptide chain. Each subunit is composed of one or more ribosomal RNA (rRNA) molecule and a variety of proteins. The ribosomes and associated molecules are also known as the translational apparatus.
