Question

Miller and Urey experiment in support of Oparin -Haldane hypothesis of chemical evolution contained which of the following gases?

I. Hydrogen gas
II. Oxygen gas
III. Methane

IV. Ammonia

• A. I and II only
• B. II only
• C. I, III and IV
• D. I, II and III
• E. II and IV

Answer 1

The correct option is C I, III and IV

Miller and Urey provided first proof for chemical synthesis of proteins by amino acids. They simulated the primitive earth conditions as proposed by Oparin and synthesized simple organic compounds (amino acids, fatty acids sugars etc.) from a mixture of methane, hydrogen, water vapour and ammonia. This makes option C correct answer.
