The article (thanks to Highlander for the tip) takes a look at the guys and gals tasked with finding out what hypothetically possible DNA sequences are not present because they code for proteins, etc. that are inimical to life. It's the DNA that could exist, but doesn't because we have selected ourselves not to have it.
Ok, so that's cool enough on it's face, but at the end was this teaser;
"Further down the line there is the possibility of constructing a "suicide gene" to code for deadly amino acid primes. It could be attached to genetically modified organisms and activated to destroy them at a later date if they turned out to be dangerous, Hampikian suggests."
- Which reminded me of....
Tyrell - "You were built as well as we could make you."
Roy - "But not to last."
