WebbRibosome biogenesis is a multistep process that includes the synthesis, processing, and folding of rRNAs, the synthesis, processing, and folding of ribosomal proteins, and finally integration of the ribosomal proteins with the mature rRNAs ( Weis et al., 2015 ). WebbRibosomes In prokaryotic cells ribosomes float freely in the cytoplasm In eukaryotic cells they are found in 2 places: 1. The cytoplasm where they may be free or attached to the surface of the endoplasmic reticulum 2. Inside mitochondria and chloroplasts Site of protein synthesis
