Which molecule carries genetic information from DNA to the ribosome for protein synthesis?

• A. tRNA
• B. DNA
• C. mRNA (messenger RNA)
• D. rRNA

Answer: (C)

Messenger RNA is the molecule that carries genetic information from DNA to the ribosome to guide protein synthesis. After DNA is transcribed, the mRNA travels to the ribosome, where its codons specify the sequence of amino acids. Transfer RNA brings the corresponding amino acids to the ribosome, reading those codons with its anticodons to assemble the protein. The idea that information flows from DNA to RNA to protein (transcription and translation) is the basis of this process. In contrast, tRNA delivers amino acids, and rRNA helps form the ribosome and catalyze peptide bond formation, while DNA remains in the nucleus. So the messenger that conveys the genetic code to the ribosome is mRNA.
