You want yeast DNA?
Lick your hand.
Lick your feet.
Lick your *beep*.
And the best thing D.N.A. is a puzzle, but a very logical one.
When you have watched bio engineering students doing their *basic* experiments with basic yeast you will be astonished what they can achieve by just playing around.
DNA is a perfect self assembling puzzle you will quickly see how things work out.
Basically what I want to lay out is that there is not just even the slightest chance of succeeding to conceal that information from drug makers, because they will find out otherwise because in DNA if it works
So yes, the cartels will find a way and hey
Also in case genetic engineering is too complex there is still Afghanistan.
1.) So you have many (and I mean many) "underpaid" bio engineering students.
2.) Decent equipment makes everything easier, but you can built that equipment, that knowledge cannot be subdued(it's too widespread)
3.) You have "fungus"(yeast) DNA everywhere
4.) Variations - If you want to find an unknown strain
5.) you have scientific journals (and you also have a black list of crap journals)
6.) Money = Resources (Hey we are talking here about drug cartels that have no problem to just loose cocain worth being 200 mUSD)
7.) We have a black pharma market that produces counterfight - and at a 50% chance high quality - drugs for old mens problems from industrial scale made basic chemicals. And nobody can stop them - or wants to.
