Question of the day

Which RNA combines with ribosomal proteins to make up the actual ribosome?

Explanation:
Ribosomes are ribonucleoprotein machines, and the RNA component—the ribosomal RNA—forms the core structure of the ribosome and contributes to its catalytic activity. Together with ribosomal proteins, rRNA creates the two subunits and provides the site where peptide bonds are formed, acting as the ribosome’s functional center. Messenger RNA is the template that carries the genetic code for the polypeptide; it binds to the ribosome during translation but does not become part of the ribosome itself. Transfer RNA brings amino acids to the growing chain but is not a structural part of the ribosome. DNA stores the genetic information and the genes for rRNA, but the ribosome itself is built from rRNA and proteins, not from DNA or the other RNAs.
