Chiral polymerisation and the RNA world
Wattis, Jonathan A.D. and Coveney, Peter V. (2005) Chiral polymerisation and the RNA world. International Journal of Astrobiology, 4 (1). pp. 63-73.
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.
