The evolution was termed as 'RNA World' on the basis of specific property of RNA molecule. This property was:

Options

A. Enzymatic property
B. Duplication property
C. Semi conservative duplication property
D. Acting as a template for protein synthesis

Answer

To answer the question regarding the property of RNA molecules that led to the term 'RNA World', we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding the RNA World Hypothesis**:
- The 'RNA World' hypothesis suggests that early life forms may have relied on RNA for both genetic information storage and catalysis before the evolution of DNA and proteins.

2. **Identifying Key Properties of RNA**:
- RNA possesses several unique properties that distinguish it from DNA and proteins. These include:
- Enzymatic activity (as ribozymes)
- Ability to replicate itself
- Serving as a template for protein synthesis

3. **Focusing on the Enzymatic Property**:
- One of the most significant properties of RNA is its ability to act as an enzyme, specifically through ribozymes. Ribozymes are RNA molecules that can catalyze biochemical reactions, similar to protein enzymes.

4. **Comparison with Other Properties**:
- While RNA can duplicate itself and serve as a template for protein synthesis, the enzymatic property is crucial because it suggests that RNA could have facilitated early biochemical reactions necessary for life.

5. **Conclusion**:
- Given the properties of RNA, the specific property that led to the term 'RNA World' is its **enzymatic property**. This means that RNA not only carried genetic information but also played an active role in catalyzing reactions.

### Final Answer:
The evolution was termed as 'RNA World' on the basis of the specific property of RNA molecule, which is its **enzymatic property**.
