In molecular biology, ribosomal ribonucleic acid (rRNA) is the RNA component of the ribosome, and is essential for protein synthesis in all living organisms. It constitutes the predominant material within the ribosome, which is approximately 60% rRNA and 40% protein by weight. Ribosomes contain two major rRNAs and 50 or more proteins. The ribosoma...
RNA that is transcribed from the DNA of the nucleolus and is found, together with characteristic proteins, in the ribosomes (see transcription).
