Ribosomes are cell organelles found within all living cells. Within a cell, ribosome may be bound to the endoplasmic reticulum, or it may be suspended in the cytosol. Ribosomes functions as the site of biological protein synthesis. They are responsible for assembling amino acids in the order specified by messenger RNA (mRNA) molecules. Ribosomes contain two parts; (i) the small ribosomal subunits (that read the RNA), and (ii) the large subunits, (that link amino acids to create a polypeptide chain).
