The Bacterial Ribosome. The bacterial ribosome is a cytoplasmic nucleoprotein particle whose main function is to serve as the site of mRNA translation and protein synthesis. The ribosome has a mass of about 2.5 MDa, with RNA accounting for 2/3 of the mass.It consists of two subunits denoted 30S (small subunit) and 50S (large).uring protein synthesis a ribosome moves along an mRNA molecule, reading the codon and adding the correct amino acid (from the corresponding aminoacyl tRNA) to the growing protein. When a stop codon is reached,translation ceases, and the mRNA and protein are released.
Ribosome. The Virtual Cell. Ribosomes are the protein assemblers of a eukaryotic cell. They are typically composed of two subunits: a large subunit and a small subunit. These two units join together to produce proteins in a process called translation.Ribosomes may be suspended in the cytosol (fluid component of the cytoplasm) of the cell or bound to the endoplasmic reticulum.Free ribosomes usually make proteins that will function in the cytosol, while bound ribosomes usually make proteins that are exported outside of the cell or included in the cell's membranes.ibosomes may be suspended in the cytosol (fluid component of the cytoplasm) of the cell or bound to the endoplasmic reticulum.
