Ribosome Diagram. Each ribosome is divided into two parts. Diameter of ribosome is 20nm.
Ribosomes from eukaryotes are larger and more complexthan those from prokaryotes but from everything we know ribosomes from all three kingdoms of life function according to the very same principles. Eukaryotic cells have 80s ribosomes with 60s larger subunit and 40s smaller subunit. Each subunit is a combination of proteins and rna called ribosomal rna rrna.
This functionality is attributed to hundreds of r genes that are present in the nucleolus.
Diameter of ribosome is 20nm. Nucleolus plays an indirect but crucial role in protein synthesis by assembling the ribosome subunits. Ribosomes in the cytoplasm of eukaryotic cells have a sedimentation coefficient of about 80 s mw about 45 x 10 6 and are composed of 40 s and 60 s subunits. The large subunit the large subunit is where the translation process takes place.
