The genetic code has many important characteristics. For example, a specific codon always means the same thing in a particular species. Codons mean the same thing in most species (even though there are some exceptions). In some cases, a particular amino acid can be specified by more than one codon (The genetic code is degenerate). Which of the following answers describes an example of the degenerate nature of the code?
A. AUU codes for Ile in a wide variety of species.
B. There are no pauses or commas in the code.
C. The sequence "AUGCCGAUU" is read as three codons, AUG, then CCG, then AUU.
D. AUU, AUC, and AUA code for Ile.
From the problem alone, it can be seen that the degeneracy of the genetic code means that more than one codon can be translated to a single amino acid.
