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.
