Dna directed synthesis of m -RNA is called

Options

A. Transcription
B. Translocation
C. Transduction
D. Replication

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the process where DNA directs the synthesis of mRNA.

2. **Analyzing the Options**:
- **Transcription**: This is the process of creating an RNA copy of a gene from the DNA. The resulting RNA is known as messenger RNA (mRNA).
- **Translocation**: This refers to the movement of a segment of DNA from one location to another within the genome, often involving chromosomes.
- **Transduction**: This is the process by which foreign DNA is introduced into a cell by a virus or a viral vector.
- **Replication**: This is the process of copying DNA to produce two identical DNA molecules.

3. **Identifying the Correct Process**: Among the options, transcription is the only process that specifically involves the synthesis of mRNA from a DNA template.

4. **Conclusion**: Therefore, the correct answer to the question "DNA directed synthesis of mRNA is called" is **Transcription**.
