Although the ribosome consists of both ribosomal RNA (rRNA) and protein, the active site on the large unit of the ribosome -- the site of the chemical reaction that changes genetic information into the beginnings of a protein -- contains only rRNA. tiny particulate structure located in the cytoplasm of the cell (outside the nucleus), the ribosome is composed of two subunits, one larger than the other. Both subunits were believed to contain both rRNA and protein but this is not the full story.
