Give an account of the Miller and Urey experiment on the origin of life.

Answer 1

In 1953 Miller and Urey conducted an experiment which established that the early Earth atmosphere was capable of producing amino acids, the building blocks of life, from inorganic substances. They took a flask containing a mixture of gases (ammonia, methane, hydrogen, water vapour) and circulated a high frequency spark in it. After a week a mixture of amino acids were obtained.
