Question

Describe the Miller's experiment related to origin of life.

Accepted Answer

Stanley L. Miller and Harold C. Urey were the two scientists who gave the experimental evidence in favour of the inanimate origin of life. According to the theory of Miller and Urey, the early Earth atmosphere was capable of producing organic molecules called amino acids, the building blocks of life, from inorganic substances. They took a mixture of water, methane, ammonia and hydrogen gas in a chamber and sparks were passed through this mixture using two electrodes. After one week, about 15% of the carbon from methane was converted into amino acids, sugars, etc. These organic molecules polymerized and assembled to form protein molecules which gave rise to life on the earth.
