The formation of DNA is a sequential process. First, the DNA molecule is transcribed on to an RNA molecule. This RNA molecule carries the information from the DNA from the nucleus to the cytoplasm, where it encounters ribosomes. The ribosomes then read the information on the RNA molecules and construct a chain of amino acids corresponding to the codons on the RNA molecule. The amino acids combine to form a protein.
Therefore, the correct sequence is C, DNA to RNA to protein.
