WebNov 13, 2015 · All living cells contain ribosomes, tiny organelles composed of approximately 60 percent ribosomal RNA ( rRNA) and 40 percent protein. However, though they are generally described as organelles, it is … WebRibosomes are composed of ribosomal RNA (rRNA) and proteins. In eukaryotes, rRNA is transcribed from genes in the nucleolus—a part of the nucleus that specializes in ribosome production. Within the nucleolus, rRNA is combined with proteins imported from the cytoplasm. The assembly produces two subunits of a ribosome—the large and the small ...
WebApr 28, 2024 · Function of a Ribosome. The function of a ribosome in any cell is to produce proteins. Proteins are used in almost all cellular functions; as catalysts they speed the time of reactions, as fibers they provide support, and many proteins function in specific tasks, like contracting muscle cells. All proteins start as deoxyribonucleic acid, or DNA.
