From his experiments, S.L. Miller produced amino acids by mixing the following in a closed flask:
A
CH₄, H₂, NH₃ and water vapor at 600°C
B
CH₃, H₂, NH₃ and water vapor at 600°C
C
CH₄, H₂, NH₃ and water vapor at 800°C
D
CH₃, H₂, NH₄ and water vapor at 800°C
Correct Answer
Option C
Detailed Explanation
In the Miller-Urey experiment (1953), S.L. Miller created a mixture of CH₄ (methane), H₂ (hydrogen), NH₃ (ammonia), and water vapor in a closed flask and subjected it to electric discharges at 800°C to simulate early Earth conditions, producing several amino acids. The correct answer is C.
