Question

Which of the following is true of prion diseases? Choose one: A. They lead to neurodegeneration. B. They have been found to contain infectious nucleic acid. C. They can be treated with antiviral medications. D. They are not transmissible.

Answer 1

A. They lead to neurodegeneration.

Step-by-step explanation:

Prions are infectious or misfolded proteins. These misfolded form of proteins is denoted as PrPsc(sc- scrapie) and this protein is able to convert the normal protein into scrapie protein.

They are responsible for causing neurodegenerative disease in humans and animals therefore they are called spongiform encephalopathies. Some of the diseases caused by prions are kuru, bovine spongiform encephalopathy, etc.

Prions do not cause disease in plants. There is no cure for these disease. Therefore the correct answer is- A. They lead to neurodegeneration.
