Which molecule serves as the intermediary carrying genetic information from DNA to the ribosome?

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

Answer: (B)

Proteins are made by translating instructions encoded in DNA into a portable template called messenger RNA. This mRNA is produced during transcription, travels from the nucleus to the ribosome, and provides the sequence that guides the assembly of amino acids into a protein. The ribosome reads the mRNA, while transfer RNA delivers the correct amino acids, and ribosomal RNA forms the ribosome itself. DNA stays as the original genetic material in the nucleus, not the intermediary that carries information to the ribosome.
