Stanley Miler had put the Oparin-Haldane theory to test in 1953 by creating in the faboratory, 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_(2),CN,H_(2) and O_(2)`
C. `H_(2),NH_(3),CH_(4) and ` water vapor
D. `NH_(3),CH_(4), and O_(2)`

Answer

**Step-by-Step Solution:**

1. **Understanding the Experiment**: The question refers to the Miller-Urey experiment conducted in 1953, which aimed to test the Oparin-Haldane theory regarding the origin of life on Earth.

2. **Identifying the Conditions**: The experiment simulated the conditions believed to be present on the early Earth. These conditions included a mixture of gases that were thought to be abundant at that time.

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

4. **Setting Up the Experiment**: The gases were placed in a closed system, and electrical sparks were introduced to simulate lightning, which was thought to provide the energy necessary for chemical reactions.

5. **Chemical Reactions**: The introduction of electrical energy caused chemical reactions among the gases, leading to the formation of organic compounds.

6. **Synthesis of Amino Acids**: After running the experiment for 18 days, the researchers observed the synthesis of simple amino acids, which are the building blocks of proteins and essential for life.

7. **Conclusion**: The amino acids were synthesized from the combination of the gases present in the closed system, specifically from methane, ammonia, hydrogen, and water vapor.

**Final Answer**: The simple amino acids were synthesized from methane, ammonia, hydrogen, and water vapor.
