Which one is obtained by S. Miller in his experiments on origin of life before 1953

Options

A. Simple sugars
B. Amino acids
C. Nucleotide
D. Peptides

Answer

**Step-by-Step Solution:**

1. **Identify the Scientist and Experiment**: The question refers to S. Miller, who is known for his experiments on the origin of life conducted in 1953.

2. **Understand the Context of the Experiment**: Miller's experiment aimed to simulate the conditions of primitive Earth to understand how organic compounds could form from inorganic substances.

3. **Describe the Experimental Setup**: In his experiment, Miller used a mixture of gases that were thought to represent the early Earth's atmosphere, including methane (CH4), ammonia (NH3), hydrogen (H2), and water vapor (H2O).

4. **Introduce Electrical Energy**: To simulate lightning, which was believed to be a common occurrence on early Earth, Miller introduced electrical sparks into the mixture.

5. **Analyze the Results**: After running the experiment for a week, Miller analyzed the contents of the flask and found that several organic compounds had formed.

6. **Identify the Key Product**: The most significant product of Miller's experiment was amino acids, which are the building blocks of proteins and essential for life.

7. **Conclude the Answer**: Based on the findings of Miller's experiment, the correct answer to the question is that he obtained amino acids.

**Final Answer**: Option B - Amino acids.
