Question

The mRNA consisting of 282 nucleotides can produce a polypeptide chain of (A) 282 amino acids (B) 120 amino acids (C) 93 amino acids (D) 94 amino acids

Each codon is a triplet in nature therefore in the given chain of mRNA there must be total of 94 codons (282/3 = 94). But if we consider the last codon as a stop codon, then polypeptide synthesized by the given mRNA has 93 amino acids.
