Miller-Urey experiment, experimental simulation conducted in 1953 that attempted to replicate the conditions of Earth's early atmosphere and oceans to test whether organic molecules could be created abiogenically, that is, formed from chemical reactions occurring between inorganic molecules thought to be present at the time. The experiment—the results of which were published in the journal ...
Miller and Urey's experiment, conducted by Stanley Miller and Harold Urey in 1953, is one of the most famous experiments in the history of biology because it demonstrated that organic molecules essential for life could be synthesized abiotically under conditions that might have existed on the early Earth. This experiment provided substantial evidence for the chemical origins of life and ...
What was the product of the Miller-Urey Experiment? Simple amino acids. Simple nucleotides. Simple lipids. Simple monosaccarides. 9. Multiple Choice. Edit. 1 minute. 1 pt. Miller/Urey and other scientists have shown that: Life on early Earth required material from space. Cells survived in the primitive atmosphere.
In 1953, Stanley Miller and Harold Urey published the results of their now famous experiment: they spontaneously produced amino acids from simple elements under conditions emulating early Earth. Given the importance of amino acids and proteins for life, this experiment was viewed as an important step toward understanding the origin of life.
The Miller-Urey experiment, [1] or Miller experiment, [2] was an experiment in chemical synthesis carried out in 1952 that simulated the conditions thought at the time to be present in the atmosphere of the early, prebiotic Earth.
The Miller-Urey experiment was the first attempt to scientifically explore ideas about the origin of life. Stanley Miller simulated conditions thought be common on the ancient Earth. The purpose was to test the idea that the complex molecules of life (in this case, amino acids) could have arisen on our young planet through simple, natural ...
