Web4 rows · Ribosomes are found ‘free’ in the cytoplasm or bound to the endoplasmic reticulum (ER) to form ... WebRibosomes are found free in the cytoplasm or on the surface of rough endoplasmic reticulum. They may exist singly or form chains (polyribosomes). Ribosomes serve as the site of protein synthesis. This is accomplished with transfer RNA (tRNA) for amino acid transport to the ribosome, and specific mRNA molecules.
