The composition of a ribosome
WebA ribosome is a molecular machine that is found in living cells. The function of these living cells is to manufacture proteins from amino acids. Ribosomes are required by the living cell to produce proteins. This whole process is known as transcription and translation or protein synthesis. Ribosomes are essential parts of any eukaryotic cell ... WebRibosomes occur in 3 sizes: 70S in bacteria and chloroplasts, 60S in mitochondria, 80S in cytoplasm of eukaryotes. All ribosomes consist of two unequal subunits each containing RNA and protein in the ratio of 63: 37. In bacteria the 70S ribosomes have 50S and 30S subunits and a diameter of 18 nm. An E. coli cell contains about 15,000 ribosomes ...
