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.
The real answer is B. Facilitated transport.
<span><span>Mitosis is the process in which cells divide to
form new cells. The cell that is being described under the microscope is
already in the Anaphase stage in mitosis.
Anaphase is the process in which two sister chromatids separate and move to
opposite poles of the cell. These two sister chromatids contain identical
copies of DNA that are joined at the middle called centromere. The chromosomes
are separated by the mitotic spindle. Towards the end of the anaphase</span> the two sister chromatids now have their two
separate poles. The mitotic process then proceeds to the
Telophase.</span>
