title: Template-directed polynucleotide synthesis on mineral surfaces.
abstract: Ferric hydroxide, a plausible prebiotic material, strongly adsorbs polynucleotides. We show that adsorption on ferric hydroxide and on several other minerals has no effect, under the conditions studied, on the template-directed oligomerization of guanylic acid on polycytidylic acid.
