Comments "Ribosomal RNAs (rRNAs) comprise 50 to 70% of the mass of the ribosomal particles. They principally determine the size and the shape of the ribosomal subunits. The rRNA molecules form a framework for specific positioning of ribosomal proteins in the ribosome. rRNA plays the leading role in ribosome function, participating in every aspect of protein synthesis. Therefore, it can be said that the ribosome is its RNA."
