The amino acid sequences of a bacterial protein and a human protein carrying out similar function are found
to be 60% identical. However the DNA sequences of the genes coding for these proteins are only 45%
identical. This is possible because-
(A) Protein sequence does not depend on DNA sequence
(B) DNA codons having different nucleotides in the third position can code for the same amino acids
(C) DNA codons having different nucleotides in the second position can code for the same amino acids
(D) Same DNA codons can code for multiple amino acids
