WebbRibosomes have size, structures and compositions similar. However, they have been divided into two groups based on the sedimentation coefficient: 70S ribosomes: They are smaller than 80S ribosomes and can be found in bacterial cells, chloroplasts and mitochondria. 80S ribosomes: The 80S ribosome is found in eukaryotic cells. WebbThe information to produce a protein is encoded in the cell’s DNA. When a protein is produced, a copy of the DNA is made (called mRNA) and this copy is transported to a ribosome.
