The correct Answer is:
To answer the question regarding the three codons that result in the termination of polypeptide chain synthesis, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Codons**: - Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids or signal the termination of protein synthesis. 2. **Identifying Start and Stop Codons**: - The process of translation begins with a start codon, which is AUG (coding for methionine). - After the polypeptide chain has been synthesized, it needs to be terminated, which is done by stop codons. 3. **Listing the Stop Codons**: - The three codons that signal the termination of polypeptide synthesis are: - UAA - UAG - UGA 4. **Conclusion**: - These three codons (UAA, UAG, UGA) are known as stop codons because they do not code for any amino acid and signal the ribosome to stop translation. ### Final Answer: The three codons that result in the termination of polypeptide chain synthesis are UAA, UAG, and UGA. ---
