Ribosomes are composed of RNA and proteins that form ribosome subunits: a large ribosome subunit and small subunit. These two subunits are produced in the nucleus and unite in the cytoplasm during protein synthesis. Free ribosomes are found suspended in the cytosol, while bound ribosomes are attached to the endoplasmic reticulum.

Ribosome | cytology | Britannica

britannica.com/science/ribosome

Ribosomes are made up of ribosomal proteins and ribosomal RNA (rRNA). In prokaryotes, ribosomes are roughly 40 percent protein and 60 percent rRNA. In eukaryotes, ribosomes are about half protein and half rRNA. Ribosomes are usually made up of three or four rRNA molecules and anywhere from about 40 to 80 different ribosomal proteins.

Ribosomes are complex particles made out of special ribosomal RNA (rRNA) and various proteins. The number of proteins varies between species. The actual physical structure of ribosomes is extraordinarily complex and consists of a deep intertwining web of RNA molecules and proteins. These molecules and proteins are arranged into two distinct ribosomal subunits of different size, known as the small and large subunit. The small and large subunit work together to synthesize proteins. The small su...
