Which of the following is not a property of the genetic code?

1. Universal
2. Non-overlapping
3. Ambiguous
4. Degeneracy

Correct answer: Ambiguous

Solution

The genetic code is universal, non-overlapping, and degenerate, but it is not ambiguous. In the standard code, each codon specifies only one amino acid or stop signal, so a codon does not have multiple meanings.
