Editing CRNs with limited geometry (section)

=== CRNs with complexation/decomplexation ===

In a 2010 paper "Turing universality of the Biochemical Ground Form" Cardelli and Zavattaro define an extension of (an equivalent language to) CRNs with operations of complexation and decomplexation, and show that the extended language (BGF) is Turing universal by emulating a register machine (where registers are stacks). But in BGF stacks are not built-in, and BGF can represent pretty much any complex dynamic polymer with a finite program.

Questions:

* Can this be useful as a formal language (analogously to CRN) to investigate expressibility questions involving polymerization?
* Is there a general DSD implementation of BGF (using DNA's ability to form complexes), the same way there is a DSD implementation of CRN?
