WebbProteins Synthesized by Free Ribosomes in the Cytoplasm So far only proteins synthesized by the ribosomes of the rough E.R. have been considered. However, most of the proteins of the mitochondria and chloroplasts are synthesized in the in the cytoplasm by free ribosomes, and are subsequently imported into these organelles, which requires … Webb14 maj 2024 · All proteins are synthesized by ribosomes using the information encoded in molecules of messenger RNA ( mRNA ). This process is called translation and is described in Gene Translation: RNA -> Protein. Our task here is to explore the ways that these proteins are delivered to their proper destinations.
