The DNA is splitting in two, thymine pairs with adenine, and guanine pairs with cytosine
Answer:
A. Prions do not contain genetic information, which is affected by ionizing radiation.
B. Denaturants may affect the tertiary structure of prions.
C. Prions are proteins.
Explanation:
Prions are the proteinaceous infectious particles that cause many degenerative diseases of neurons in both animals and humans. They consist of only protein and no DNA or RNA. Due to the absence of DNA or RNA as genetic material, these infectious particles are resistant to ionizing radiation. Ionizing radiations affect nucleic acids of pathogens to destroy them.
Denaturation of proteins affects their secondary and tertiary structures and leave them non-functional. Denaturation may be caused by changes in temperature, pH, disturbance of hydrogen bonds, etc. Therefore, to destroy prions, they need to be denatured.

Does that mean in order? if not the answer is C
Answer:
When the cell cycle is interrupted, apoptosis occurs.
Explanation:
Opoptosis is also known as programmed death of the abnormal cell. When cell DNA is damaged first it is repaired. If cell DNA cannot be repaired so the cell kill itself. If Opoptosis didn't occurs, then the cell divides with the damage DNA and transfer that damage DNA to the daughter cells which lead to cancer disease. Cancer also occurs when uncontrolled division of cells is done.
