Chiral polymerisation and the RNA world

Wattis, Jonathan A.D.; Coveney, Peter V.

Abstract

The purpose of this paper is to review two mathematical models: one
for the formation of homochiral polymers from an originally chirally
symmetric system; and the other, to show how, in an RNA-world scenario,
RNA can simultaneously act both as information storage
and a catalyst for its own production. We note the similarities and
differences in chemical mechanisms present in the systems.
We review these two systems, analysing steady-states,
interesting kinetics and the stability of symmetric solutions.
In both systems we show that there are ranges of parameter values where
some chains increase their own concentrations faster than others.
