alt Hacker NewsI’m pretty sure they were talking about how you can combine synthesized oligos into longer fragments when you are starting with smaller oligos. I’m guessing that they were referring to using different restriction enzymes from that point on.
Unless we are talking about really long oligos (which is harder and $$$), you’ll need some post-synthesis enzymatic work to get your full strand.
Yes I also read the comment that way. The inkjet printer remark presumably refers to benchtop DNA synthesis machines which have been commercially available for a while now. (The linked article mentions the possibility of buy-back programs for old machines that don't enforce any restrictions.)
I guess it's not a bad idea to put basic hurdles in place but it would be a serious mistake to see this as any sort of comprehensive preventative. DNA just isn't difficult to manipulate.
