The possibility that the infective agent may not contain nucleic acid and consist only of a peptide or peptide-polysaccharide complex which has replication properties within susceptible cells is intriguing. If peptides, short-chain proteins, or peptide/fatty-acid/ polysaccharide complexes activate nucleic-acid template activity in the host genes to produce identical infective particles, this would invalidate the accepted dogma of present-day molecular biology in which D.N.A. and R.N.A. templates control all biological activity.
