WebA ribosome is made out of RNA and proteins, and each ribosome consists of two separate RNA-protein complexes, known as the small and large subunits. The large subunit sits on top of the small subunit, with an RNA template sandwiched between the two. It is in practical terms a ratio of demand to supply of nutrients. The demand will be …
