Prions cannot destroy brain tissue.
A
True
B
False
Explanation: 

Detailed explanation-1: -Prion diseases occur when normal prion protein, found on the surface of many cells, becomes abnormal and clump in the brain, causing brain damage.

Detailed explanation-2: -Prion diseases are transmissible, untreatable, and fatal brain diseases of mammals. Their cause is highly unusual: The host’s normal prion protein can, for unknown reasons, malfunction and assemble into structured aggregates called prions that cause infectious brain disease.

Detailed explanation-3: -To destroy a prion it must be denatured to the point that it can no longer cause normal proteins to misfold. Sustained heat for several hours at extremely high temperatures (900°F and above) will reliably destroy a prion.

Detailed explanation-4: -Which is true about prions?-They are naked pieces of RNA.
