Due to discovery of which of the following in 1980, the evolution was termed as RNA world :

Options

A. m-RNA,t-RNA synthesise proteins
B. In some virus RNA is genetic material
C. RNA have enzymatic property
D. RNA is not found in all cells.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the discovery in 1980 that led to the term "RNA world" being used in the context of evolution.

2. **Identifying the Key Concept**: The term "RNA world" refers to the hypothesis that RNA was the first genetic material and played a crucial role in early life forms. This concept emerged from the understanding that RNA can serve both as genetic material and as a catalyst for biochemical reactions.

3. **Exploring the Discoveries**: In the 1980s, significant discoveries were made regarding the properties of RNA. One of the pivotal discoveries was that RNA molecules could have enzymatic functions, which means they could catalyze reactions, similar to proteins.

4. **Evaluating the Options**: The options provided in the question likely include various aspects of RNA. The correct option should highlight RNA's ability to act as both genetic material and a catalyst.

5. **Selecting the Correct Answer**: The most appropriate answer to the question is that RNA has enzymatic properties. This discovery was crucial in supporting the idea of an "RNA world," where RNA was fundamental to early life processes.

6. **Conclusion**: The discovery of RNA's enzymatic properties in the 1980s led to the concept of the "RNA world," indicating that RNA was likely the first genetic material and played a key role in the evolution of life.

**Final Answer**: The evolution was termed as RNA world due to the discovery that RNA has enzymatic properties.
