method by which information reaches from DNA to RNA is :-

Options

A. Trascription
B. Translation
C. Transformation
D. Transduction

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the method by which information is transferred from DNA to RNA.

2. **Identifying the Options**: The options provided are:
- Transcription
- Translation
- Transformation
- Transduction

3. **Analyzing Each Option**:
- **Transcription**: This is the process where the information in a DNA strand is copied into a new molecule of messenger RNA (mRNA). This is the direct transfer of genetic information from DNA to RNA.
- **Translation**: This process involves converting the sequence of the mRNA into a sequence of amino acids to form proteins. It does not involve the transfer of information from DNA to RNA.
- **Transformation**: This refers to the uptake of naked DNA by a cell, typically in bacteria. It does not describe the process of transferring information from DNA to RNA.
- **Transduction**: This is the process by which foreign DNA is introduced into a cell via a virus. Again, this does not pertain to the transfer of information from DNA to RNA.

4. **Conclusion**: Based on the definitions and processes described, the correct method by which information reaches from DNA to RNA is **Transcription**.

**Final Answer**: Transcription
