Solution

The correct option is A UAA
The codons that cause termination of protein synthesis are known as stop/terminator codons. The DNA stop codons are TAG, TAA and TGA. The corresponding RNA stop codons are UAG, UAA and UGA. "AUG" is the most common start codon. The presence of termination codon in the ribosomal A site is followed by hydrolysis of the terminal peptidyl-tRNA bond to release the polypeptide and the last tRNA and finally dissociation of the 70S ribosome into its 30S and 50S subunits. The start codon specifies the first codon of mRNA transcript that is translated by a ribosome. It codes for methionine in eukaryotes and a modified Met in prokaryotes.
