Detailed explanation-1: -In this brilliant experiment, Miller and Urey demonstrated that electrical sparking a mixture of methane, ammonia, and hydrogen in the presence of water produces amino acids within a variety of organic compounds.

Detailed explanation-2: -The Miller-Urey experiment was the first attempt to scientifically explore ideas about the origin of life. The purpose was to test the idea that the complex molecules of life (in this case, amino acids) could have arisen on our young planet through simple, natural chemical reactions.

Detailed explanation-3: -The experiments reported were conducted by Stanley L. Miller, then a graduate student working under the direction of Harold C. Urey at the University of Chicago chemistry department. The mixture of gases used was methane, ammonia, water and hydrogen.

Detailed explanation-4: -The primary significance of the Miller-Urey experiment was that the experiment significantly proved that origin of life on the planet Earth had occurred because of the chemical conditions or through Abiogenesis. During the investigation, the reactants that were used were water, methane, ammonia, and hydrogen.
