The genetic code is described as redundant because
A.several codons can specify the same amino acid
B.each codon specifies several amino acids
C.the code differs in every species
D.codons are only two bases long
Explanation
Core Concept
61 codons encode 20 amino acids, so most amino acids have multiple codons — redundancy that buffers the effects of some mutations.
Correct Answer
Aseveral codons can specify the same amino acid
