MDCAT 2026 MCQs

Reverse transcriptase copies viral RNA into DNA.
The viral DNA can then integrate into the host genome.

Volume at STP = moles × 22.4 L mol⁻¹.
The calculated volume is 33.6 L.

Loss of helper T cells impairs immune coordination.
Normally controlled organisms can then cause serious disease.

Volume at STP = moles × 22.4 L mol⁻¹.
The calculated volume is 44.8 L.

Loss of helper T cells impairs immune coordination.
Normally controlled organisms can then cause serious disease.

Volume at STP = moles × 22.4 L mol⁻¹.
The calculated volume is 67.2 L.

Loss of helper T cells impairs immune coordination.
Normally controlled organisms can then cause serious disease.

Kc contains product concentrations over reactant concentrations.
Each concentration is raised to its stoichiometric coefficient.

Charles’s law gives V₁/T₁ = V₂/T₂.
V₂ = 3×400÷300 = 4 L.

Kc contains product concentrations over reactant concentrations.
Each concentration is raised to its stoichiometric coefficient.

Charles’s law gives V₁/T₁ = V₂/T₂.
V₂ = 5×300÷250 = 6 L.

Kc contains product concentrations over reactant concentrations.
Each concentration is raised to its stoichiometric coefficient.
