生物学基础入门

For many years, we just thought RNA was a DNA photocopier as mRNA, the protein builder, as tRNA, and found in ribosomes as rRNA.

许多年来,我们只是认为 RNA 是作为 mRNA 的 DNA 复印机,作为 tRNA 的蛋白质构建者,并作为 rRNA 在核糖体中发现。

小亚基核糖体RNA的5'端域,来自Rfam数据中。该例子是:RF00177

核糖体RNAribosomal RNA, rRNA)是生物细胞中主要的核糖核酸之一,是一种具有催化能力的核糖酶,但其单独存在时不能发挥作用,仅在与多种核糖体蛋白质共同构成核糖体(一种无膜细胞器)后才能执行其功能。23S和28S rRNA在翻译过程中作为肽酰转移酶催化多肽(包括蛋白质)中氨基酸之间肽键的形成。rRNA是单链RNA,但通过折叠形成了广泛的双链区域。

Ribosomal RNA 核糖体核糖核酸

(重定向自RRNA)
Three-dimensional views of the ribosome, showing rRNA in dark blue (small subunit) and dark red (large subunit). Lighter colors represent ribosomal proteins.
Small subunit ribosomal RNA, 5' domain taken from the Rfam database. This example is RF00177

In molecular biology, ribosomal ribonucleic acid (rRNA) is the RNA component of the ribosome, and is essential for protein synthesis in all living organisms. It constitutes the predominant material within the ribosome, which is approximately 60% rRNA and 40% protein by weight. Ribosomes contain two major rRNAs and 50 or more proteins. The ribosomal RNAs form two subunits, the large subunit (LSU) and small subunit (SSU). The LSU rRNA acts as a ribozyme, catalyzing peptide bond formation. rRNA sequences are widely used for working out evolutionary relationships among organisms, since they are of ancient origin and are found in all known forms of life.
