RNA diversification by a self-reproducing ribozyme revealed by deep sequencing and kinetic modelling

Chem Commun (Camb). 2021 Jul 29;57(61):7517-7520. doi: 10.1039/d1cc02290c.

Abstract

We demonstrate that a recombinase ribozyme achieves multiple functions in the same reaction network: self-reproduction, iterative elongation and circularization of other RNAs, leading to synthesis of diverse products predicted by a kinetic model. This shows that key mechanisms can be integrated and controlled toward Darwinian evolution in RNA reaction networks.
