What is the significance of the Miller-Urey experiment in the context of organic chemistry?
A
It demonstrated that organic molecules could be synthesized from inorganic precursors under prebiotic conditions.
B
It confirmed that DNA is the only molecule capable of storing genetic information.
C
It proved that life originated from outer space through panspermia.
D
It showed that organic molecules are unstable and cannot form naturally.

The Miller-Urey experiment was designed to simulate the conditions thought to be present on the early Earth and test the chemical origins of life.
In the experiment, a mixture of gases (methane, ammonia, hydrogen, and water vapor) was subjected to electrical sparks to mimic lightning, which was believed to be a common energy source on early Earth.
After running the experiment for a week, the resulting mixture was analyzed and found to contain several organic compounds, including amino acids, which are the building blocks of proteins.
This experiment provided evidence that organic molecules necessary for life could be formed from simple inorganic precursors under conditions similar to those of early Earth.
The significance of the Miller-Urey experiment in organic chemistry is that it demonstrated the potential for abiotic synthesis of organic molecules, supporting theories about the chemical origins of life on Earth.
