Which of the following is not associated with prions?

a. Replicating shapes

b. Mad cow disease

c. DNA

d. Toxic proteins

Prions, unlike other infectious agents like bacteria, viruses, and fungi, lack genetic materials like DNA and RNA. Prions' distinct characteristics and genetic information are thought to be encoded in the proteins' conformational structure and posttranslational modifications.

Prions can enter the cerebrum through contamination, or they can emerge from changes in the quality that encodes the protein. When present in the cerebrum prions increase by inciting harmless proteins to refold into the strange shape.

A cow gets BSE by eating feed debased with parts that came from another cow that was debilitated with BSE. The debased feed contains the unusual prion, and a cow becomes tainted with the strange prion when it eats the feed.

Prions are infectious agents that are made up entirely of protein and have no DNA or RNA. They appear to cause death by duplicating their shapes and accumulating in tissues. They're thought to play a role in a variety of progressive brain diseases, such as mad cow disease and Creutzfeldt-Jakob disease.

Prions are irresistible specialists made out of polymers of misfolded prion protein which cause lethal mind infections like Creutzfeldt-Jakob sickness. These illnesses include moderate loss of neuronal cells, and it has been for quite some time accepted that prions are straightforwardly poisonous to cells as they proliferate.

DNA is not linked to prions.
