Origin of ribosomal RNA:
Ribosomal ribonucleic acid is the RNA component of the ribosome, and is essential for protein synthesis in all living organisms. It comprises the predominant material within the ribosome, which is ca. 60% rRNA and 40% protein by weight. Ribosomes contain two major rRNAs and 50 or more proteins. The LSU and SSU rRNAs are found within the large and small ribosomal subunits, respectively. The LSU rRNA acts as a ribozyme, catalyzing peptide bond formation. rRNA sequences are widely used for working out evolutionary relationships among organisms, since they are of ancient origin and are found in all known forms of life.
