Select the correct statement for transcription.

Options

A. Transfer of genetic code of RNA to DNA
B. Transfer the information of genetic codes of mRBA to form protein
C. Transfer of genetic code of DNA to RNA
D. Polymerisation of dexyribouncleotides in cell - free system

Answer

To determine the correct statement regarding transcription, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding Transcription**:
- Transcription is the process where the genetic information encoded in DNA is copied into messenger RNA (mRNA). This occurs in the nucleus of eukaryotic cells.

2. **Analyzing the Statements**:
- **Statement 1**: "Transfer of genetic code of RNA to DNA."
- This statement is incorrect. Transcription involves the transfer of genetic information from DNA to RNA, not the other way around.

- **Statement 2**: "Transfer of the information of genetic code of mRBA to form protein."
- This statement is misleading. While it is true that mRNA carries the genetic code for protein synthesis, this process is called translation, not transcription. Therefore, this statement is also incorrect.

- **Statement 3**: "Transfer of genetic code of DNA to RNA."
- This statement is correct. During transcription, the information in the DNA is transcribed into mRNA, which is the essence of the transcription process.

- **Statement 4**: "Polymerization of deoxyribonucleotides in cell-free system."
- This statement is incorrect in the context of transcription. Transcription involves the polymerization of ribonucleotides (not deoxyribonucleotides) to form RNA.

3. **Conclusion**:
- The only correct statement regarding transcription is **Statement 3**: "Transfer of genetic code of DNA to RNA."

### Final Answer:
The correct statement for transcription is: **"Transfer of genetic code of DNA to RNA."**
