Question:
Which of the following is a stop codon:
Which of the following is a stop codon:
Show Hint
Remember the Stop Codons: UAA, UAG, and UGA (âU Go Awayâ).
Updated On: May 28, 2026
- UAC
- UGG
- UGA
- UAU
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
The genetic code consists of 64 codons, most coding for amino acids, while others signal termination.
Step 2: Meaning
Stop codons do not code for any amino acid and signal the ribosome to release the polypeptide.
Step 3: Analysis
Three stop codons: UAA (Ochre), UAG (Amber), and UGA (Opal). UAC and UAU code for Tyrosine; UGG codes for Tryptophan.
Step 4: Conclusion
Among the options, UGA is the correct stop codon.
Final Answer: (C)
