Answer: a polypeptide that consists of 4 amino acids

Explanation:

Using the genetic code, a codon or a triplet of bases specifies an amino acid. There is a 15 nucleotide sequence including a stop codon. Thus, we have 3 nucleotide each specifying for an amino acid including the start codon which in eukaryotes codes for methionine and in prokaryotes formyl methionine but excluding the stop codon/termination codon which does not specify for any amino acid.

So, we will have a polypeptide chain of 4 amino acids (3 nucleotides in four places gives 12 nucleotide sequence).
