WebRibosomes are macromolecular machines that catalyse the synthesis of proteins from amino acids; synthesis and assembly into subunits takes place in the nucleolus and includes the association of ribosomal RNA (rRNA) with ribosomal proteins translocated from their site of synthesis in the cytoplasm. Ribosomes are compositionally heterogeneous between species and even within the same cell, as evidenced by the existence of cytoplasmic and mitochondria ribosomes within the same eukaryotic cells. Certain researchers have suggested that heterogeneity in the composition of ribosomal proteins in mammals is important for gene regulation, i.e., the specialized ribosome hypothesis. However, this hypothesis is controversial and the topic of ongoing research.
