The RNAi stand for-

Options

A. RNA inactivation
B. RNA initiation
C. RNA interference
D. RNA interferon

Answer

**Step-by-Step Solution:**

1. **Understanding the Acronym**: The question asks for the meaning of the acronym "RNAi". To answer this, we need to break down the components of the acronym.

2. **Identifying the Options**: The options provided are:
- RNA inactivation
- RNA initiation
- RNA interference
- RNA interferon

3. **Analyzing Each Option**:
- **RNA inactivation**: This suggests a process where RNA is made inactive, but it is not the standard term used in molecular biology.
- **RNA initiation**: This refers to the beginning of RNA synthesis, which is not related to the acronym RNAi.
- **RNA interference**: This is a well-known biological process that involves the regulation of gene expression and is indeed represented by RNAi.
- **RNA interferon**: This term does not correspond to any recognized biological process related to RNAi.

4. **Selecting the Correct Answer**: Based on the analysis, the correct answer is "RNA interference", as it accurately describes the process associated with the acronym RNAi.

5. **Conclusion**: Therefore, RNAi stands for "RNA interference".
