the doctor email laing dm day. and a just and just this? >> i did talk at length about this. dna synthesis is done by big companies. you can design your own sequence said it to the lab then you get back in a vital but they are pretty good at spotting bad stuff. you don't know how they work but we trust them to protect us from that. but what of those are on every desktop? then they say we ensure there is intelligence that when you're sequence comes said, it needs to pass the test and only then. right now by the photocopier impasse to look for a u.s. currency. but they did not let you do order to put a big water mark over it. we do have some precedence we can check to make sure bad stuff does not have been. that is craig's best answer. i am an optimist. never anticipate things ahead of time. the notion of the test-tube baby. actually thought they would grow the babies in test tubes. [laughter] i was a little confused. now it is called in vitro fertilization but we were playing god and it was super scary then we said it is not so scary. cologne is like we're test-tube baby was.
