Final answer:
The genetic code is transcribed from DNA to mRNA, which travels to the cytoplasm to be interpreted by ribosomes, on a stage and a catalytic power provided by tRNA.
Step-by-step explanation:
The genetic code is transcribed from DNA to mRNA, which travels to the cytoplasm to be interpreted by ribosomes, on a stage and a catalytic power provided by tRNA. So, the correct option is (a) mRNA, ribosomes, tRNA.
