Find out the incorrect match.

Options

A. UUU - Phenylalanine
B. UAG - Sense codon
C. GUG - Valine
D. UGG - Tryptophan

Answer

To solve the question of finding the incorrect match among the codons and their corresponding amino acids, we can follow these steps:

### Step 1: Identify the Codons and Their Corresponding Amino Acids
We need to analyze each codon provided in the question and determine whether the amino acid match is correct.

### Step 2: Analyze Each Codon
1. **UUU**: This codon codes for **Phenylalanine**.
- **Match**: Correct.

2. **UAG**: This codon is known as a **stop codon** (or non-sense codon), meaning it does not code for any amino acid. The question states it is a sense codon.
- **Match**: Incorrect.

3. **GUG**: This codon codes for **Valine**.
- **Match**: Correct.

4. **UGG**: This codon codes for **Tryptophan**.
- **Match**: Correct.

### Step 3: Conclusion
The only incorrect match is **UAG**, as it is a stop codon and does not correspond to any amino acid.

### Final Answer
The incorrect match is **UAG as a sense codon**.
