Find out the incorrect match

Options

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

Answer

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

### Step-by-Step Solution:

1. **Identify the Codons and Their Corresponding Amino Acids**:
- UUU - Phenylalanine
- UAG - Arginine
- GUG - Valine
- UGG - Tryptophan

2. **Check Each Codon Against the Genetic Code**:
- **UUU**: This codon is known to code for Phenylalanine. This match is correct.
- **UAG**: This codon is a known stop codon and does not code for any amino acid. The claim that it codes for Arginine is incorrect.
- **GUG**: This codon is known to code for Valine. This match is correct.
- **UGG**: This codon is known to code for Tryptophan. This match is correct.

3. **Determine the Incorrect Match**:
- From the analysis, UAG is incorrectly matched with Arginine since it is a stop codon and does not code for any amino acid.

### Conclusion:
The incorrect match is **UAG - Arginine**.
