The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Codons**: The question provides three codons: UAG, UAA, and UGA. These are part of the genetic code used during protein synthesis. 2. **Identifying Codon Types**: Codons can be categorized into different types based on their function in protein synthesis. There are initiator codons (start codons) and terminator codons (stop codons). 3. **Recognizing Initiator and Terminator Codons**: - The initiator codon is responsible for signaling the start of protein synthesis. The most common initiator codon is AUG. - Terminator codons signal the end of protein synthesis. The codons UAG, UAA, and UGA are known as stop codons. 4. **Conclusion**: Since UAG, UAA, and UGA are identified as stop codons, they serve as terminator codons in the translation process. 5. **Final Answer**: Therefore, the correct answer to the question is that UAG, UAA, and UGA codes serve as **terminator codons**. ---
