Question

Stanley Miller had put the Oparin-Haldane theory to test in $1953$ by creating in the laboratory, the probable conditions on the primitive Earth. In the experiment, simple amino acids were synthesized from the following mixtures as observed after $18$ days

• A. $H_{2},O_{2},N$ and $H_{2}O$
• B. $CH_{4},CN,H_{2}$ and $O_{2}$
• C. ${{H}_{2}},N{{H}_{3}},C{{H}_{4}}$ and water vapour
• D. $N{{H}_{3}},C{{H}_{4}}$ and ${{O}_{2}}$

Answer 1

Answer: (C)

Miller $(1953)$ set an experiment to test the Oparin-Haldanes theory. He created primitive atmosphere like conditions by sealing in a spark chamber, a mixture of water vapour $\left( H _{2} O \right)$, methane $\left( CH _{4}\right)$, ammonia $\left( NH _{3}\right)$ and hydrogen gas $\left(H_{2}\right)$. After eighteen days, significant amount of the simple major organic compounds (monomers), such as ammo acids and peptide chains, began to appear in the aqueous sample of the experimental set.
