Evolution to Complexity: Replication, Elongation and Assembly in an RNA World
Tomoyuki Yamajnoto · 2007
A spatially resolved model of RNA world is studied, where primer induced replication, concatenation and random cutting are considered. The increase of diversity of sequences and complexity of shapes axe observed; A hierarchically orgnized replication network is formed, and evolution to long sequences and assembly of further long sequences are obtained through it. These results suggest a scenario for overcoming the error threshold and for the evolution of enzymatic activity.
