Comparison of the same gene and its product in two different animal species revealed that the amino acids are 98 percent identical but the nucleotides are only 86 percent identical.What accounts for the much higher amino acid identity than nucleotide identity?
A) The genetic code is redundant.
B) The genetic code differs between species.
C) The researchers sequenced different template strands.
D) The genetic code is nonredundant.
E) The genetic code is ambiguous.

The genetic code is redundant, meaning that different nucleotide sequences can code for the same amino acid. Therefore, changes in nucleotides may not necessarily lead to changes in amino acids, resulting in a higher level of amino acid identity compared to nucleotide identity.
