Eric Lander: I have a very important job for you. We have analyzed tissues from a group of sisters from one family and found high concentrations of a certain protein. However, other than the initial methionine, deciphering its peptide chain has been more difficult than usual. I'm enlisting you to crack this for me.
You: What does the protein do, exactly?
Lander: It seems the gene that produces it predisposes individuals to travel to far off places. Any country you can name, they've either already visited or are planning to!
You: That's quite the affliction! Can I take a look at the chain you have so far?

Hmm, it seems to be country-coded. And a couple aren't like the others.
Lander: I trust that you can figure it out. Please report back to me with any interesting findings!
