The process by which DNA of the nucleus passes genetic information of m-RNA is called-

Options

A. Transcription
B. Translocation
C. Translation
D. Transportation

Answer

To solve the question "The process by which DNA of the nucleus passes genetic information to mRNA is called-", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for the specific process that involves the transfer of genetic information from DNA to mRNA.

2. **Identify the Relevant Processes**: The options provided are:
- Transcription
- Translocation
- Translation
- Transportation

3. **Recall the Central Dogma of Molecular Biology**: According to Francis Crick's central dogma, genetic information flows from DNA to RNA to protein. This means that DNA is first transcribed into RNA (specifically mRNA), which is then translated into a protein.

4. **Define Each Option**:
- **Transcription**: The process of synthesizing mRNA from a DNA template.
- **Translocation**: The movement of a segment of DNA from one location to another within the genome.
- **Translation**: The process of synthesizing proteins from mRNA.
- **Transportation**: The movement of RNA from the nucleus to the cytoplasm.

5. **Determine the Correct Answer**: Since the question specifically asks about the process where DNA is used to create mRNA, the correct answer is **Transcription**.

6. **Conclusion**: Therefore, the process by which DNA of the nucleus passes genetic information to mRNA is called **Transcription**.

### Final Answer:
**Transcription**
