WebPrions are proteinaceous infectious particles that lack nucleic acids and replicates by converting similar normal proteins into new prions. Their replication process is like a parasite where it infects the cell and denatures its proteins to make it into a prion. Even though prions are not living like viruses, prions are different from viruses.
