Which one of the following is wrongly matched?

Options

A. Operon - Structural genes, operator and promoter
B. Transcription - Writing information from DNA to t-RNA
C. Translation - Using information in m-RNA to make protein
D. Repressor protein - Binds to operator to stop enzyme synthesis

Answer

To determine which option is wrongly matched, let's analyze each of the provided matches step by step.

### Step-by-Step Solution:

1. **Operon with Structural Genes, Operator, and Promoter**:
- An operon is a functional unit of genomic DNA containing a cluster of genes under the control of a single promoter. It includes structural genes, an operator, and a promoter.
- **Conclusion**: This match is correct.

2. **Transcription with Writing Information from DNA to tRNA**:
- Transcription is the process where the information in DNA is copied into messenger RNA (mRNA), not tRNA. tRNA is involved in translation, not transcription.
- **Conclusion**: This match is incorrect.

3. **Translation with Polymerization of Amino Acids**:
- Translation is the process where the mRNA is decoded to synthesize proteins, which involves the polymerization of amino acids into polypeptide chains.
- **Conclusion**: This match is correct.

4. **Repressor Protein Binds to the Operator to Stop Enzyme Synthesis**:
- The repressor protein binds to the operator region of the operon to prevent transcription of the structural genes, thereby inhibiting the synthesis of the enzymes coded by those genes.
- However, it does not stop the synthesis of RNA polymerase; it prevents the transcription process.
- **Conclusion**: This match is misleading but essentially correct in context, as it refers to stopping enzyme synthesis indirectly by preventing transcription.

### Final Conclusion:
The wrongly matched option is the second one: "Transcription with Writing Information from DNA to tRNA."
