Question

Select the correct statement that describes the effect of the result of Urey-Miller experiment on the Oparin hypothesis.

• A. The results supported the Oparin hypothesis by showing that organisms contributed to the composition of Earths present-day atmosphere
• B. The results contradicted the Oparin hypothesis by showing that Earths early atmosphere could not produce cells from organic molecules
• C. The results supported the Oparin hypothesis by showing that replicating membranes could form from simple molecular precursors
• D. The results contradicted the Oparin hypothesis by showing that Earths early atmosphere was too hot and volatile to sustain living things
• E. The results supported the Oparin hypothesis by showing that biological molecules could form in conditions resembling the early Earth

Answer 1

The correct option is E The results supported the Oparin hypothesis by showing that biological molecules could form in conditions resembling the early Earth

The results supported the Oparin hypothesis by showing that biological molecules could form in conditions resembling the early Earth.

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 under those conditions. The experiment confirmed Alexander Oparin's and J. B. S. Haldane's hypothesis that putative conditions on the primitive Earth favoured chemical reactions that synthesized more complex organic compounds from simpler inorganic precursors. Considered to be the classic experiment investigating abiogenesis, it was conducted in 1952 by Stanley Miller, with assistance from Harold Urey, at the University of Chicago and later the University of California, San Diego and published the following year.
