Question
Which of the following was formed in S Miller’s experiment?
- Amino acids
- Nucleic acids
- UV radiations
- Microspheres
The correct answer is: Amino acids
In 1953, Stanley Miller synthesized organic compounds under conditions resembling the primitive atmosphere of the earth, a mixture of water vapour, methane, hydrogen and ammonia was circulated through a closed apparatus by steam from boiling water and subjected to an electric spark discharge (7000V) between tungston electrodes. This apparatus was permitted to run for a week. The result was several amino acids.
