Miller and Urey performed an experiment to prove the origin of life. They took gases NH₃ and H₂ alongwith

Options

(a) N₂ and H₂O
(b) CH₄ and N₂
(c) H₂O and CH₄
(d) CO₂ and NH₃

Correct Answer:

H₂O and CH₄

Explanation:

The Miller-Urey experiment tested for the occurrence of chemical evoution. This experiment was conducted in 1953 at the University of Chicago. The experiment used water (H₂O),Methane (CH₄), ammonia (NH₃) and hydrogen (H₂) The chemicals were all sealed inside a sterile array of glass half-full of liquid water and another flask contining a pair evaproation, sparks were fired through the atmosphere and was cooled again so that the water could condense and tricles back into the first flask in a continuous cycle. At the end of one week of continuous operation, Urey and Miller observed that as much as 10-15% of the carbon within the system was now in the form of organic compounds. they found a large number of simple organic compounds, including some amino acids such as alanine, glycine and sapartic acid.
