Editing DNA computing (section)

=== Chemical reaction networks (CRNs) ===
The full stack for DNA computing looks very similar to a traditional computer architecture. At the highest level, a C-like general purpose programming language is expressed using a set of [[Chemical reaction networks|chemical reaction networks (CRNs)]]. This intermediate representation gets translated to domain-level DNA design and then implemented using a set of DNA strands. In 2010, Erik Winfree's group showed that DNA can be used as a substrate to implement arbitrary chemical reactions. This opened the way to design and synthesis of biochemical controllers since the expressive power of CRNs is equivalent to a Turing machine.<ref name=":0" /><ref name=":1" /><ref name=":2" /><ref name=":3" /> Such controllers can potentially be used ''in vivo'' for applications such as preventing hormonal imbalance.
