Question

The Miller-Urey experiment provided evidence for which stage of the origin of life?

K SUNKANNA · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [C]
## CONCEPT FRAMEWORK
	**Primary Concept**: Abiotic synthesis of organic compounds
	**Related Topics**: Origin of life, Prebiotic chemistry
	**Prerequisites**: Basic understanding of organic chemistry and the conditions of early Earth
## SOLUTION PATHWAY
**Given Information**:
		- The Miller-Urey experiment simulated early Earth conditions.
		- It aimed to test the hypothesis of abiogenesis by creating organic compounds from inorganic precursors.
**Method & Steps**:
	1.	Identify the purpose of the Miller-Urey experiment.
		Reasoning: The experiment was designed to explore how organic molecules could form from simple inorganic substances under conditions thought to resemble those of early Earth.
		Formula/Rule: N/A
	2.	Analyze the results of the experiment.
		Working: The experiment produced amino acids, which are the building blocks of proteins, indicating that organic monomers could form spontaneously.
		Key Point: The formation of these organic compounds supports the idea that life could arise from non-living matter.
	3.	Conclude the significance of the findings.
		Result: The evidence supports the theory of abiotic synthesis of organic monomers, which are crucial for the development of life.
		Verification: The production of amino acids and other organic molecules confirms the hypothesis tested in the experiment.
## OPTION ANALYSIS
[A] :x: Formation of the first cells - This option is incorrect as the Miller-Urey experiment did not address the formation of cells directly.
[B] :x: Evolution of photosynthesis - This option is incorrect as it relates to biological processes that occurred after the formation of organic compounds.
[C] ✓: Abiotic synthesis of organic monomers - This is the correct option as it directly correlates with the findings of the Miller-Urey experiment.
[D] :x: Development of self-replicating molecules - This option is incorrect, as the experiment did not demonstrate self-replication but rather the formation of basic organic compounds.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the stages of the origin of life: Understand the difference between abiotic synthesis and biological evolution.
		2. Misunderstanding the experiment's purpose: Remember that it was primarily about organic compound formation.
	**Quick Tips**:
		1. Remember the key products of the Miller-Urey experiment: amino acids and other organic molecules.
		2. Link the experiment back to the broader context of abiogenesis to reinforce understanding.
