Question

The RNA world hypothesis proposes that RNA was the primary genetic material in early life. Which of the following properties of RNA supports this hypothesis?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [B]
## CONCEPT FRAMEWORK
	**Primary Concept**: RNA World Hypothesis
	**Related Topics**: Origin of Life, Genetic Material, Catalytic Activity of RNA
	**Prerequisites**: Basic knowledge of DNA and RNA structure and function
## SOLUTION PATHWAY
**Given Information**:
	* The RNA world hypothesis proposes RNA as the primary genetic material in early life.
	* We need to identify a property of RNA that supports this.
**Method & Steps**:
	1. Analyze each option and compare it to the requirements of a primary genetic material.
		Reasoning: A primary genetic material needs to both store information and carry out catalytic functions.
	2. Evaluate option A: RNA is more stable than DNA - this is not true. DNA is more stable than RNA.
	3. Evaluate option B: RNA can act as both a carrier of genetic information and a catalytic enzyme - this is correct because it fulfills both requirements.
	4. Evaluate option C: RNA is double-stranded - this is incorrect, RNA is single stranded.
	5. Evaluate option D: RNA cannot be degraded by enzymes - this is incorrect, RNA can be degraded by enzymes.
**Result**: The correct option is B.
	Verification: Option B satisfies the requirement of a primary genetic material having both information storage and catalytic capabilities.
 ## OPTION ANALYSIS
[A] :x: RNA is less stable than DNA, not more stable.
[B] ✓: RNA's ability to act as both a carrier of genetic information and a catalytic enzyme (ribozymes) is a key piece of evidence supporting the RNA world hypothesis.
[C] :x: RNA is typically single-stranded, not double-stranded.
[D] :x: RNA can be degraded by enzymes called ribonucleases.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing RNA stability with DNA stability. RNA is less stable.
		2.[Error 2]: Thinking all RNA is only for information storage, forgetting about ribozymes.
	**Quick Tips**:
		1.[Helpful shortcut]: Remember 'RNA can do both' - store information and act as an enzyme.
		2.[Memory aid]: Think of ribozymes as enzymes made of RNA.

Mr. NARESH KUMAR K · Answer

RNA is more stable than DNA.

Mr. NARESH KUMAR K · Answer

The correct Option is "RNA can act as both a carrier of genetic information and a catalytic enzyme."

Mr. NARESH KUMAR K · Answer

RNA is double-stranded, providing redundancy in genetic information.

Mr. NARESH KUMAR K · Answer

RNA cannot be degraded by enzymes.
