WebReplication in prions: Propagation in prions is done by transmitting a misfolded protein state. Upon its entry into a healthy organism, the prion induces the conversion of properly-folded proteins into the disease-associated- prion form. This can then act as a template to guide the misfolding of more proteins into prion form. Suggest Corrections.
