These transcriptors are practically assemblers that do nano-chemistry! I’m not sure if Eric Winfree was the first to say this; but, i recall hearing him say that the Ned Seeman dna-nanotechnology actually works better in cells than out of them. So, here, we have transcriptors/assemblers, and by doing the Ned Seeman dna-nanotechnologies inside the cell, the nanochemistry can be self-organised inside the cell by Seeman-dnananostructures.

Cells are covered by pores that allow certain chemicals in and excrete certain products or even waste. I think that dna-nanostructures punctured into cells has already been demonstrated. So, we could extend the self organising of transcriptor products inside the cell and put a super-pore on the cell that allows the self-organised nanomechanical whatever outside to an extended Seeman/Rothemund dna-structure which can do more assembly.
