Some amino acids are coded by more than one codon, hence the genetic code is

Options

A. overlapping
B. degenerate
C. wobbled
D. unambiguous

Answer

To answer the question regarding the nature of the genetic code, we will analyze the options provided and determine which one correctly describes the genetic code based on the information given.

### Step-by-Step Solution:

1. **Understand Codons**: Codons are sequences of three nucleotides that correspond to specific amino acids. Each codon can code for one or more amino acids.

2. **Identify the Options**: The question provides several options regarding the nature of the genetic code:
- Overlapping
- Degenerate
- Wobble
- Unambiguous

3. **Evaluate Each Option**:
- **Overlapping**: This option suggests that codons overlap with each other. This is incorrect because the genetic code is non-overlapping, meaning that each nucleotide is part of only one codon.
- **Degenerate**: This option indicates that some amino acids can be coded by more than one codon. This is correct; for example, the amino acid phenylalanine can be coded by the codons UUU and UUC.
- **Wobble**: This term refers to the flexibility in base pairing at the third position of a codon. While it is a feature of the genetic code, it does not directly imply that some amino acids are coded by more than one codon.
- **Unambiguous**: This means that each codon specifies only one amino acid. This is also correct but does not address the question about multiple codons coding for the same amino acid.

4. **Conclusion**: The correct answer is that the genetic code is **degenerate** because it allows for some amino acids to be coded by more than one codon.

### Final Answer:
The genetic code is **degenerate**.
