Summary on Grant Application Form
Replication is the cornerstone of the success of biological systems. The behaviour of replicating systems has many attractive features that are of interest to synthetic chemists. If we can learn to design and exploit replication in a purely synthetic, i.e. non-biological context, the development of cleaner and more efficient synthetic routes to important compounds becomes possible. The cooperation and interaction between replication systems in biology is key to evolving more complex behaviour. This behaviour is termed hypercyclic and encompasses features such as feedback loops and amplification of specific products. This project aims to investigate, develop and exploit this hypercyclic behaviour in synthetic systems. The outcome of this research programme is very hard to predict a priori. It is possible, though unlikely based on our preliminary simulations, that placing different replicating systems in competition or cooperation might simply lead to each system inhibiting the operation of the others. If this scenario emerges, that this result in itself is important in that it places certain constraints on the emergence and the identity of early replicators on the prebiotic earth. If, however, we can evolve complex hypercyclic cooperative behaviour, such as feedback loops and amplification, then we will have demonstrated that complex behaviour is ubiquitous and by careful design can be harnessed to whatever synthetic end is demanded by the chemist. This proposal aims to address these issues through a programme of fundamental and systematic studies of minimal and reciprocal replication and their interactions with the goals of both exposing the basic physical organic chemistry of replication and developing an integrated design framework for replicating systems with which to move forward.
