As mentioned above, ribosomes are the molecular machines responsible for protein synthesis. A 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.
Ribosomes are called protein factories because the proteins are manufactured in the ribosomes.The proteins are made up of amino acids (smaller units).
