Which one the following is wrongly matched ?

Options

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

Answer

To determine which of the following statements is wrongly matched, we need to analyze each statement carefully:

1. **Transcription**: The statement claims that transcription is "writing information from mRNA to make protein."
- **Correct Definition**: Transcription is the process of synthesizing RNA from a DNA template. It involves the conversion of DNA to mRNA, not the other way around.
- **Conclusion**: This statement is **incorrect**.

2. **Translation**: The statement claims that translation is "using information in the mRNA to make protein."
- **Correct Definition**: Translation is indeed the process where the information encoded in mRNA is used to synthesize proteins.
- **Conclusion**: This statement is **correct**.

3. **Repressor Protein**: The statement claims that a repressor protein binds to the operator to stop enzyme synthesis.
- **Correct Definition**: A repressor protein does bind to the operator region of an operon to inhibit the expression of genes, thereby stopping enzyme synthesis.
- **Conclusion**: This statement is **correct**.

4. **Operon Structure**: The statement claims that an operon has structural genes, an operator, and a promoter.
- **Correct Definition**: An operon indeed consists of structural genes that encode proteins, an operator that regulates gene expression, and a promoter that initiates transcription.
- **Conclusion**: This statement is **correct**.

**Final Conclusion**: The only statement that is wrongly matched is the first one regarding transcription.

### Summary of the Solution:
- The first statement about transcription is incorrect because it misrepresents the process as mRNA to protein instead of DNA to mRNA.
- The other statements regarding translation, repressor proteins, and operon structure are correct.
