DNA vaccines (tested in mice) use the gene for the immunogenic protein and coat it with what element, which is injected into cells and results in antibody production?

Correct Answer: D

Rationale: DNA vaccines use gold particles to deliver genes into cells, triggering protein expression and antibody production.

Correct Answer: B

Rationale: G6PD deficiency impairs NADPH production, mimicking CGD by reducing oxidative burst in phagocytes.

Correct Answer: C

Rationale: A hapten is a small molecule that can bind to antibodies but cannot induce an immune response unless attached to a carrier protein.

Correct Answer: A

Rationale: Hyperacute rejection is mediated by preformed antibodies that bind donor antigens, triggering immediate graft damage.

Correct Answer: D

Rationale: B cells exhibit allelic exclusion, but the expression of maternal or paternal alleles varies between individuals, though typically only one allele is expressed per B cell.
