Select the correct statement for transcription.

Options

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

Answer

To solve the question regarding the correct statement for transcription, let's break down the options provided and analyze them step by step.

### Step 1: Understand the process of transcription
Transcription is the biological process through which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). This process involves the synthesis of RNA from a DNA template.

### Step 2: Analyze the options
1. **Transfer of genetic code of RNA to DNA**: This statement is incorrect because transcription involves the synthesis of RNA from DNA, not the reverse.

2. **Transfer the information of genetic codes of messenger RNA to form protein**: This statement describes translation, not transcription. Translation is the process where mRNA is used to synthesize proteins.

3. **Transfer of genetic code of DNA to RNA**: This statement accurately describes transcription. During transcription, the genetic information in DNA is transcribed into RNA.

4. **Polymerization of deoxyribonucleotides in cell-free system**: This statement is incorrect in the context of transcription. It refers to DNA synthesis, which is not the focus of transcription.

### Step 3: Identify the correct statement
From the analysis, the correct statement regarding transcription is:
- **Transfer of genetic code of DNA to RNA**.

### Conclusion
The correct answer is the third option: **transfer of genetic code of DNA to RNA**.
