    "abstract": "We propose a model for chiral polymerisation and investigate its symmetric\nand asymmetric solutions. The model has a source species which decays into\nleft- and right-handed types of monomer, each of which can polymerise to form\nhomochiral chains; these chains are susceptible to `poisoning\u0027 by the opposite\nhanded monomer. Homochiral polymers are assumed to influence the proportion of\neach type of monomer formed from the precursor. We show that for certain\nparameter values a positive feedback mechanism makes the symmetric steady-state\nsolution unstable. The kinetics of polymer formation are then analysed in the\ncase where the system starts from zero concentrations of monomer and chains. We\nshow that following a long induction time, extremely large concentrations of\npolymers are formed for a short time, during this time an asymmetry introduced\ninto the system by a random external perturbation may be massively amplified.\nThe system then approaches one of the steady-state solutions described above.",
