Security by obscurity is not cryptography. I presume the used a complementary sequence to the tagged message (if they used the message itself as a tag, they obviously cheated).

What's the point? For several years you can order an oligo by sending an email with the desired sequence, the Eppendorf caps coming with the mail. Probably you can even outsource the ligation with PCR nowadays. Digesting unspecific DNA is easy, so is mixing, so is complementary matching, so is sequencing. So, where's the beef?

Now, if they found a message from God/aliens buried down in some conserved gene somewhere, now that would be really interesting.
