Which RNA type decodes the genetic message during protein synthesis?

• A. Ribosomal RNA
• B. Messenger RNA
• C. Transfer RNA
• D. Small nuclear RNA

Answer: (B)

The message being read during protein synthesis is carried by messenger RNA. It contains codons that specify the order of amino acids to be assembled into the protein. During translation, the ribosome uses this mRNA sequence as a guide, while transfer RNA brings the corresponding amino acids by matching its anticodons to the mRNA codons. The ribosome’s RNA (rRNA) helps form the machinery and catalyze peptide bonding, but it’s the mRNA that provides the actual coded message to be translated. Small nuclear RNA, on the other hand, is involved in RNA processing, not translation.
