Which of the following best describes the importance of similar amino acid sequencing of a protein in different organisms?
A The sequence of amino acids in a protein does not directly reflect the DNA that encodes the protein.
B The more differences there are in the amino acid sequencing, the fewer the mutations in their DNA.
C Fewer differences in the amino acid sequencing of a protein show a greater evolutionary relatedness.
D The fewer differences there are in the amino acid sequencing, the less closely the organisms will be related.
