Detailed explanation-1: -They were of the idea that the early earth’s atmosphere was able to produce amino acids from inorganic matter. The two biologists made use of methane, water, hydrogen, and ammonia which they considered were found in the early earth’s atmosphere.

Detailed explanation-2: -In 1953, scientist Stanley Miller performed an experiment that may explain what occurred on primitive Earth billions of years ago. He sent an electrical charge through a flask of a chemical solution of methane, ammonia, hydrogen and water. This created organic compounds including amino acids.

Detailed explanation-3: -In addition to the sulfur-containing organic compounds, Miller’s unreported 1958 H2S experiment also generated amino acids such as threonine, leucine, and isoleucine, which were not detected in the other three discharge experiments.

Detailed explanation-4: -The study shows that Miller–Urey experiments produce RNA nucleobases in discharges and laser-driven plasma impact simulations carried out in a simple prototype of reducing atmosphere containing ammonia and carbon monoxide.

Detailed explanation-5: -Urey and Miller showed the synthesis of organic compounds which included amino acids such as glycine, alanine and aspartic acid.
