Question

.................. performed experiment to prove modern theory of origin of life.

• A. Urey and Miller
• B. Haldane
• C. Oparin
• D. Darwin and Lamarck

Answer 1

The correct option is A Urey and Miller

The Miller Urey experiment was a chemical experiment that simulated the conditions thought at the time to be present on the early Earth and tested the chemical origin of life. Specifically, the experiment tested Alexander Oparin and J. B. S. Haldane's hypothesis (that is the modern theory of origin of life) that conditions on the primitive Earth favoured chemical reactions that synthesize more complex organic compounds from simpler inorganic precursors. Considered to be the classic experiment investigating abiogenesis, it was conducted in 1952 by Stanley Miller, under the supervision of Harold Urey, at the University of Chicago and later the University of California, San Diego and published the following year. The experiment used water (H${}_2$O), methane (CH${}_4$), ammonia (NH${}_3$), and hydrogen (H${}_2$).
Therefore, the correct answer is option A.
