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.
Prokaryotic and eukaryotic ribosomes are both made of rRNA and proteins, but the subunits are going to be different sizes. In addition, a group of bacteria can perform photosynthesis like plants. Without a chloroplast organelle, a bacterium can perform photosynthesis in the folds of its cell membrane.
