Stanley Miler had put the Oparin-Haldane theory to test in 1953 by creating in the laboratory, the probable conditions on the primitive earth. In the experiment simple aminoacids were synthesized from which of the following modures, as observed after eighteen days?

Options

A. `H_(2),O_(2),N_(2)` and `H_(2)O`
B. `CH_(4),CN,H_(3)` and `O_(2)`
C. `H_(2),NH_(3),CH_(4)` and water vapour
D. `NH_(3),CH_(4)` and `O_(2)`

Answer

To solve the question regarding Stanley Miller's experiment in 1953, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**:
- Stanley Miller conducted an experiment to test the Oparin-Haldane theory regarding the origin of life on Earth. This theory suggested that simple organic compounds could form under prebiotic conditions.

2. **Identify the Experiment Setup**:
- Miller created a closed system that simulated the conditions of primitive Earth. This included a mixture of gases and a water source to mimic the early atmosphere and oceans.

3. **List the Gases Used**:
- The gases that Miller used in his experiment included:
- Hydrogen (H₂)
- Ammonia (NH₃)
- Methane (CH₄)
- Water vapor (H₂O)

4. **Observation After 18 Days**:
- After running the experiment for 18 days, Miller observed the formation of simple amino acids, which are the building blocks of proteins.

5. **Conclusion**:
- The simple amino acids were synthesized from the inorganic molecules (hydrogen, ammonia, methane, and water vapor) present in the experimental setup.

### Final Answer:
The simple amino acids were synthesized from the following inorganic molecules: **Hydrogen, Ammonia, Methane, and Water Vapor**.
