    "abstract": "A fully self-contained model of homochirality is presented that contains the\neffects of both polymerization and dissociation. The dissociation fragments are\nassumed to replenish the substrate from which new monomers can grow and undergo\nnew polymerization. The mean length of isotactic polymers is found to grow\nslowly with the normalized total number of corresponding building blocks.\nAlternatively, if one assumes that the dissociation fragments themselves can\npolymerize further, then this corresponds to a strong source of short polymers,\nand an unrealistically short average length of only 3. By contrast, without\ndissociation, isotactic polymers becomes infinitely long.",
