Ribosomes are synthesized in the nucleolus by combining rRNA which is made there and ribosomal proteins that are synthesized in the cytoplasm and are imported into the nucleus. The ribosome is exported out of the nucleus and into the cytoplasm or are deposited on the rough ER. Ribosomes do not become fully active until they leave the nucleus.
In eukaryotes, ribosomes form in the nucleolus, a structure inside the cellâs nucleus. As ribosomal proteins enter the nucleus, they join with four rRNA strands to create a complete ribosome. The subunits exit the nucleus through pores and begin protein synthesis in the cytoplasm of the cell. In prokaryotes, proteins combine with three rRNA strands. Since prokaryotes do not have a membrane-bound nucleus, ribosomes form within the cytoplasm.
