In numerous studies, treatment of prion preparations with ionizing and UV-radiation does not reduce transmission of disease. however, treatment with denaturants reduces disease transmission What can be interred from these observations? Choose all the true statements

Prions are smaller than viruses, which are affected by radiation.
Denaturants may affect the tertiary structure of prions.
Prions do not contain genetic information, which is affected by ionizing radiation.
Prions are proteins

Prions do not contain genetic information, which is affected by ionizing radiation.

Explanation:

Prions are the infectious protienaceous infectious particle. They are infectious protiens. THey are normal body protiens that get converted into an alternate configuration by contact with other prion protiens. THey have no DNA or RNA. THe main protien involved in human and mammalian prion diseases is call Prp.

As the prions doesn't have DNA and RNA, thus lack genetic information, hence the option Prions do not contain genetic information, which is affected by ionizing radiation is correct
