Find out in this USA Today article how DNA sequences can vouch for a souvenir's authenticity.

open Background Essay

Wherever there's an item of value, from artwork to currency to GucciTM bags, there are counterfeits. But now science has offered a new and perhaps foolproof method of tagging genuine items: DNA sequences. As this USA Today article reports, DNA sequences from Olympic athletes were used in the ink on Sydney 2000 Olympic souvenirs. The only remaining question is, Will the DNA hold up in the wash?

open Discussion Questions

  • How were Sydney 2000 Olympics souvenirs labeled with DNA?
  • Would you want to wear clothing that contains someone else's DNA? Why or why not?
  • Would it be possible for a counterfeiter to copy the DNA and produce undetectable counterfeit items? If so, would it be worthwhile for them to do so?
  • Do you think the DNA will hold up in the wash?
