Question:
Gargi constructed m-RNA in laboratory. Which of the following codons will she have as initiating and terminating the m-RNA respectively?
Gargi constructed m-RNA in laboratory. Which of the following codons will she have as initiating and terminating the m-RNA respectively?
Show Hint
{Start codon = AUG; Stop codons = UAA, UAG, UGA}.
Updated On: Mar 6, 2026
- AUG–UAG
- GUG–UAC
- UAC–AUG
- AUG–UCA
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding start and stop codons.
Protein synthesis begins at a specific start codon and ends at a stop codon on m-RNA.
Step 2: Identifying correct codons.
AUG is the universal initiation codon coding for methionine.
UAG is one of the three termination (stop) codons.
Step 3: Conclusion.
Thus, the initiating and terminating codons are AUG–UAG.
Protein synthesis begins at a specific start codon and ends at a stop codon on m-RNA.
Step 2: Identifying correct codons.
AUG is the universal initiation codon coding for methionine.
UAG is one of the three termination (stop) codons.
