Depictions of left-handed DNA are easy to come by. Here are some example answers to the left-handed DNA challenge [1]:
  1. 1.

    On a stamp: (1) 1964 Israeli stamp, or (2) 2002 Italian stamp

     
  2. 2.

    On a banknote: Turkish five-lira banknote

During your next chemistry conference trip, pay close attention to the gamut of logos of biotechnology companies, almost all of which nowadays incorporate an image of the DNA double helix. You will be surprised how many of them feature the infamous left-handed DNA. Many more examples of left-handed DNA can be found on the World-Wide Web. In particular, noteworthy is Tom Schneider’s virtual gallery, the Left Handed DNA Hall of Fame [2].
