Prions multiply by a process which is, at present, not fully understood. The protein PrPr is present in healthy cells of all mammals, in the brain and central nervous system. It is only when the gene that creates PrPr undergoes mutation that it begins to produce a harmful strain of PrPr, the prion. Prions replicate by causing the surrounding healthy proteins to fold abronmally, turning them into prions. These newly-formed prions in turn cause other proteins to fold abnormally. This process creates vacuoles in the cells of the brain, resulting in diseases such as Creutzfeld-Jakob disease in humans, and Bovine Spongiform Enphysema in cows.

Prions are made up only of proteins and lack nucleic acids.
They contain only protein and no nucleic acids
Much larger, prions are just proteins containing no nucleic acids or lipid bilayer.
Nucleic acids are carbon compounds that store and transmit genetic information. They include:Deoxyribonucleic acid (DNA)Ribonucleic acid (messenger,transfer) (RNA)proteins (in the case of prions)

They aren't. Life on earth could not exist without nucleic acids.

Nucleic acids.
Nucleic acids are polymers of nucleotides.
what are the building blocks of nucleic acids?
Nucleic acids make proteins.
They are the nucleotides . They make up nucleic acids
