The amino acid sequences of a bacterial...

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 are found

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
