PROOF OF CONCEPT
Our proof of concept lies within use of a promoter library and a concept of randomly assorted DNA fragments, are they truly random? This is not yet completed, but will be before the Jamboree.
Proof is arbitrary
The idea of proof is relative, there is no proof that can truly make an idea or theory a certainty. Proofs can only make an idea more certain, at least in the non-mathematical sense.
However for details of modelling "proofs" to make the idea of our experiment more certain, check the modelling pages.
