The nucleotide structural component of ribosomes is what?

The nucleotide structural component of ribosomes is what?

• A. rRNA
• B. mRNA
• C. tRNA
• D. DNA

Answer: (A)

Ribosomes are ribonucleoprotein particles, and the nucleic acid that forms the core structure and catalytic part of the ribosome is ribosomal RNA (rRNA). The rRNA molecules fold to create the ribosome’s framework and the peptidyl transferase center, which coordinates the translation of mRNA into protein. Messenger RNA carries the genetic code from DNA to the ribosome, and transfer RNA brings in the specific amino acids, while DNA serves as the genetic template that is transcribed into RNA. So the nucleotide component that constitutes the ribosome is rRNA.
