Enzyme DNA dependent RNA polymerase is used in

Options

A. Ribosome synthesis
B. mRNA symthesis
C. DNA synthesis
D. Carbohydrate synthesis

Answer

**Step-by-Step Solution:**

1. **Understanding the Enzyme**: The enzyme in question is DNA dependent RNA polymerase. This enzyme plays a crucial role in the synthesis of RNA from a DNA template.

2. **Identifying the Process**: The primary function of DNA dependent RNA polymerase is to synthesize messenger RNA (mRNA) during the process known as transcription. This is when the genetic information encoded in DNA is copied into RNA.

3. **Analyzing the Options**:
- The first option mentions ribosome synthesis, which involves the enzyme peptidyl transferase, not DNA dependent RNA polymerase.
- The second option refers to mRNA synthesis, which is indeed the correct function of DNA dependent RNA polymerase.
- The third option discusses DNA synthesis, where DNA polymerase is the key enzyme involved.
- The fourth option talks about carbohydrate synthesis, which involves different enzymes such as transaldolase.

4. **Conclusion**: Based on the analysis, the correct answer is the second option, which states that DNA dependent RNA polymerase is used in mRNA synthesis.

**Final Answer**: DNA dependent RNA polymerase is used in mRNA synthesis.
