Which statement best describes the role of mrna in protein synthesis? a. stores the genetic code in the nucleus. b. splits the dna molecule into two strands. c. carries an amino acid to the ribosome. d. copies the genetic code from the dna molecule and carries it to the ribosome.

The right answer is D.

The messenger ribonucleic acid, messenger RNA or mRNA is a transient copy of a portion of the DNA corresponding to one or more genes. mRNA is used as an intermediate by cells for protein synthesis. The concept of messenger RNA was issued and demonstrated by Jacques Monod, François Jacob and their collaborators in 1960.
