In this article we will discuss about the chemical composition and structure of ribosomes. Chemical Composition of Ribosomes: Ribosomes are made of RNA and protein. In E. coli, they contain 34% protein and 66% RNA, while in eukaryotes, they contain 40% protein and 60% RNA. Chemical composition of large subunit is different from that of small subunit. The size and [...]
