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 big complexes of protein and RNA molecules. In eukaryotic cells: Most of the ribosomal RNA is made in a specialized region of the nucleus called the nucleolus with only exception the 5s rRNA which is made in different part of the nucleus.he Nucleolus is also found in the nucleus. It produces ribosomes at a rate of 10,000 / min. The nucleus controls the cell's functioning through the production of m-RNA. Ribosomes: functions in protein synthesis. They are not considered a membrane bound organelle. Ribosomes are built from 2 subunits.
