Typical of mammalian mitochondrial ribosomes, the bovine mitochondrial ribosome has been developed as a model system for the study of human mitochondrial ribosomes, to address several questions related to

Ribosomal protein synthesis in eukaryotes is a major metabolic activity. It occurs, like most protein synthesis, in the cytoplasm just outside the nucleus. Individual ribosomal proteins are synthesized and imported into the nucleus through nuclear pores. See nuclear import for more about the movement of the ribosomal proteins into the nucleus.
