Question
Which mRNA will be translated to a polypeptide chain containing 8 amino acids?

Solution
AUG is the initiating codon that encodes for methionine.
Stop codon is a triplet of nucleotides sequence presence on mRNA, which terminates the process of translation and protein synthesis. These do not code for any amino acid. There are three stop codons, viz., UAG, UGA and UAA.
Option A will encode - MET LEU ILE ASP GLU STOP
Option B will encode - MET ARG ARG THR ALA PHE PRO THR STOP
Option C will encode - MET PRO ASN ARG TYR SER CYS STOP
Option D will encode - MET SER THR VAL STOP
AUGAGACGGACUGCAUUCCCAACCUGA will be translated to a polypeptide chain containing 8 amino acids.
So the correct option is B - AUGAGACGGACUGCAUUCCCAACCUGA
