Immune System Test Quizlet Questions
Question 1 of 5
Determine the following diseases that are not thought to be an autoimmune disease.
Correct Answer: C
Rationale: The correct answer is C, Cancer of the bone marrow. Autoimmune diseases occur when the immune system mistakenly attacks healthy cells. Rheumatoid arthritis, multiple sclerosis, and insulin-dependent diabetes are autoimmune diseases where the immune system targets specific tissues or organs. Cancer of the bone marrow, on the other hand, is a result of uncontrolled cell growth and division, not a malfunction of the immune system attacking the body's own tissues. Therefore, it is not considered an autoimmune disease.
Question 2 of 5
An essential cofactor for restriction endonuclease enzyme activity is
Correct Answer: B
Rationale: The correct answer is B: Mg2+. Mg2+ is an essential cofactor for restriction endonuclease enzymes because it stabilizes the enzyme-substrate complex, promotes proper binding of the enzyme to DNA, and facilitates the catalytic activity of the enzyme. Mg2+ ions help in the coordination of the active site residues and the phosphate backbone of DNA, which is crucial for the cleavage of DNA strands. Zn2+, Co2+, and Ca2+ do not provide the necessary coordination and stabilization required for restriction endonuclease enzyme activity, making them incorrect choices.
