Which molecule carries the genetic message from the nucleus to the ribosome during protein synthesis?

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

Answer: (A)

Messenger RNA carries the genetic message from the nucleus to the ribosome. It is produced by transcription of a DNA gene, then travels to the cytoplasm where its codons guide the ribosome in assembling the corresponding amino acids into a protein. Transfer RNA brings each amino acid to match a codon, and ribosomal RNA helps form the ribosome and catalyze peptide bond formation. DNA stays in the nucleus as the storage of genetic information, while mRNA serves as the readable message that directs protein synthesis.
