C) nascent protein
D) codons

If tRNAs charged with radioactively labeled amino acids are added to an in vitro experiment with all components needed for protein synthesis, the radioactivity would eventually localize in the nascent protein being synthesized. This is because the radioactively labeled amino acids are being incorporated into the protein chain as it is being synthesized on the ribosome. The other choices - mRNA, aminoacyl tRNA synthetase, and codons - would not be directly involved in incorporating the labeled amino acids into the protein.
