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).

> lastly, "it's not that bad for you" often, markets and cig stores tell potential buyers its not as bad as other things. Some say its not harmful at all.( Lung disease,gum disease,heart failure,etc. all disprove this. Each year about 480,000 people die from the affects of smoking)
