Which molecule carries the genetic code from DNA to the ribosome during protein synthesis?

Explanation:
Messenger RNA is the molecule that carries the genetic code from DNA to the ribosome during protein synthesis. It’s produced during transcription from a DNA template and then travels to the ribosome, where its codons specify the sequence of amino acids to be added. Transfer RNA brings the corresponding amino acids to the ribosome, while ribosomal RNA forms the ribosome itself and helps catalyze peptide bond formation. DNA remains in the nucleus and does not leave to the ribosome.
