Solution
The correct option is A UAA
The stop codon is the code of the three nucleotides in the segment of the mRNA which results in the termination of the activity of the ribosome during the process of translation. The protein which is formed gets released when the ribosome reaches the stop codon. The codons UAG, UGA and UAA are known as the stop codons. There are no anticodons or tRNA for this stop codons. So, the presence of these codons results in termination of the process.Thus, the correct answer is option A.
