The triplet code can produce 64 possible codon combinations. What is an advantage of this? A. Every single codon specifies more than one amino acid. B. Every single amino acid has more than one codon. C. The first two bases of the codon specify the amino acid.

Sincere there are 64 codons (61 of them coding) and only 20 amino acids, there are many more codons than amino acids.  For this reason, the genetic code is said to be redundant.

However, the answer they give as B (and expect to be correct) is not correct.  In the "Universal" genetic code, two amino acids have only a single codon (methionine and tryptophan).

so its not b is it a

anonymous · Answer

No, it's definitely not A.  A is completely wrong.
The answer they want is B.
What I am saying is that B is not completely correct (but they don't realize it).

o ok thank you

C is tricky.  Usually that is true but not always.  Look at the code.
