Q. 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

AMUAMU 2012Evolution

Solution:

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.
