Question

The experiment that replicated circumstances that were expected to exist on the early earth?

  1. Hershey–Chase experiment
  2. Geiger–Marsden experiment
  3. Miller–Urey experiment
  4. Schiehallion experiment

hintHint:

The experiment that replicated circumstances that were expected to exist on the early earth is Miller–Urey experiment.

The correct answer is: Miller–Urey experiment


    • It is an experiment created by Harold Urey and Stanley Miller.
    • It can be seen as a simulation of early earth.
    • They tested the Oparin-Haldane theory.
    • This experiment produces the organic molecule needed for early life on earth.
