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.
Newton's law of gravity defines the attractive force between all objects that possess mass. Understanding the law of gravity offers profound insights into the way our universe functions. Newton, upon observing an apple fall from a tree, began to think along the following lines: The apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that acts on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "acceleration due to gravity". Then imagine the apple tree is twice as high. Again, we expect the apple to be accelerated toward the ground, so this suggests that this force that we call gravity reaches to the top of the tallest apple tree. <span>Newton knew that the force which caused the apple's acceleration (gravity) must be dependent upon the mass of the apple. And since the force acting to cause the apple's downward acceleration also causes the earth's upward acceleration (Newton's third law), that force must also depend upon the mass of the earth. </span>
This structure encapsulates the pituitary gland to aid in protection and diffusion of releasing hormones from the anterior pituitar is Sella Turcica.
Sella Turcica it is very important during embryological development , mainly help in migration of Neural crest cell to frontonasal . This neural crest help in development of teeth and Sella Turcica
What is Neural crest cell ?
- A multipotent and migrating cell population called neural crest cells (NCCs) helps the developing embryo generate a variety of tissues. A group of disorders and illnesses called as neurocristopathies are caused by flaws in the growth, differentiation, and migration of NCCs.
- Found in ectoderm in the margin of the neural tube
- Contribute in the formation of a plethora of different tissues and organs
- Its includes melanocytes, bone of smooth muscle
