Which RNA type carries instructions from DNA to the ribosome for protein synthesis?

• A. Ribonucleic Acid
• B. Messenger RNA
• C. Transfer RNA
• D. Ribosomal RNA

Answer: (B)

Genetic information is transcribed from DNA into RNA and then translated at the ribosome to make proteins. The RNA that serves as the template carrying that instructional code from DNA to the ribosome is messenger RNA. It’s produced by transcription, leaves the nucleus, and provides a sequence of codons that the ribosome reads to determine the order of amino acids in the growing polypeptide. Each codon specifies a particular amino acid, guiding the assembly process during translation. Other RNA types have different roles, so they don’t carry the instructional template to the ribosome. Transfer RNA delivers individual amino acids to the ribosome by matching its anticodon to the mRNA codon, effectively translating the code into a chain of amino acids. Ribosomal RNA is a structural and catalytic component of the ribosome itself, helping to form the ribosome’s active site and facilitate peptide bond formation. The term RNA alone doesn’t designate the informational messenger, so the specific carrier of the message to the ribosome is the messenger RNA.
