Question

S.L. Miller created electric discharge in a closed flask and observed amino acids formation by mixing which of the following components at 800°C?

• A. H${}_2$, O${}_2$, CH${}_4$, H${}_2$O
• B. CH${}_3$, CO${}_2$, H${}_2$, H${}_2$O
• C. CH${}_4$, H${}_2$, NH${}_3$, H${}_2$O
• D. CH${}_3$, H${}_2$, SO${}_2$, H${}_2$O

Answer 1

The correct option is C CH${}_4$, H${}_2$, NH${}_3$, H${}_2$O

S.L. Miller produced amino acids by mixing CH${}_4$, H${}_2$, NH${}_3$ and water vapour at 800°C.

Oparin and Haldane proposed a hypothesis. According to this hypothesis, the first form of life came from pre-existing non-organic molecules.

S.L. Miller supported their proposal. He created Earth's reducing atmosphere during the early days of development.
He created electric discharge in a closed flask containing methane, hydrogen, ammonia, and water vapour at 8000C. This resulted in the formation of amino acids.

Thus, the correct answer is (C).
