A) The RNA base sequence determines the DNA base sequence which, in turn, determines the protein amino acid sequence.
B) The DNA base sequence determines the RNA base sequence which, in turn, determines the protein amino acid sequence.
C) The DNA base sequence determines the protein amino acid sequence which, in turn, determines the RNA base sequence.
