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

Options

A. Universal
B. Non-overlapping
C. Ambiguous
D. Degeneary

Answer

To determine which of the following is not a property of the genetic code, we need to analyze each option provided:

1. **Universal**: The genetic code is universal, meaning that it is the same in almost all organisms. This property indicates that the same codons code for the same amino acids across different species.

2. **Non-overlapping**: The genetic code is non-overlapping, which means that each nucleotide in the sequence is part of only one codon. Codons are read in a linear fashion without overlapping.

3. **Ambiguous**: The genetic code is not ambiguous. This means that each codon specifies only one amino acid. For example, the codon UUU always codes for phenylalanine. Therefore, the genetic code is non-ambiguous.

4. **Degeneracy**: The genetic code is degenerate, which means that multiple codons can code for the same amino acid. For instance, both UUU and UUC code for phenylalanine.

From this analysis, we can conclude that the property that is not associated with the genetic code is **ambiguous**.

### Final Answer:
The correct answer is **ambiguous**.
