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.
The ribosome (/ËraÉªbÉµËzoÊm/) is a large and complex molecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules.Ribosomes consist of two major components: the small ribosomal subunit, which reads the RNA, and the large subunit, which joins amino acids to form a polypeptide chain.Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and a variety of proteins.igure 1: The ribosome assembles polymeric protein molecules whose sequence is controlled by the sequence of messenger RNA molecules. This is required by all living cells and associated viruses.
