To crack the genetic code, researchers introduced synthetic messenger RNAs into in vitrotranslation systems and determined which proteins were produced from these synthetic mRNAs. mRNAs consisting of poly-UUC led to production of three different proteins: poly-Phe, poly-Ser, and poly-Leu. What best explains this result?
A. Each amino acid is specified by several codons.
B. Transcription started at three different places.
C. The synthetic mRNA was read in all three reading frames.
D. Each codon codes for several different amino acids.
