Peter Palmer asked the Naked Scientists:
Since both DNA strands have a 3' end, and I know of no means a cell can differentiate sense from anti-sense, (other than potentially distance to the centromere), is there a reason a reverse complement incorporating the combined promoter and starter sequences is unlikely, in order to avoid spurious primary transciptions?

What do you think?

Reading complementary DNA is likely to end up hitting a "STOP" codon fairly quickly?
...But this would still leave a lot of short junk RNA sequences floating around...
