Question
Which of the following gases were used in Urey-Miller’s experiment?
- Methane, carbon-di-oxide, ammonia, and water vapor
- Methane, hydrogen, ammonia, and water vapor
- Methane, hydrogen cyanide, ammonia, and water vapor
- Oxygen, carbon di-oxide, ammonia, and water vapor
Hint:
The Urey Muller experiment was a chemical experiment that demonstrates origin of life from the primitive condition of the earth
The correct answer is: Methane, hydrogen, ammonia, and water vapor
- Urey Muller experiment used water methane hydrogen and water.
- They prepared the same condition as they thought the primitives earth would have.
- Continuous ekectric sparks were fired to simulate the lightening in the water vapour and gaseous mixture
- The chemical reactions occurred that produced amino acids such as glycine and alanine
