Which antibiotic inhibitis interaction between tRNA and mRNA

Options

A. Tetracycline
B. Eythromycin
C. Neomycin
D. Streptomycin

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for an antibiotic that inhibits the interaction between tRNA (transfer RNA) and mRNA (messenger RNA) during the process of protein synthesis (translation).

2. **Role of tRNA and mRNA**: In the process of translation, mRNA carries the genetic information from DNA, and tRNA brings the appropriate amino acids to the ribosome, where the mRNA is translated into a protein. The interaction between tRNA and mRNA is crucial for the correct assembly of amino acids into proteins.

3. **Impact of Inhibition**: If the interaction between tRNA and mRNA is inhibited, protein synthesis cannot occur, leading to the death of the bacteria or pathogen, as they rely on protein synthesis for survival.

4. **Identifying Antibiotics**: Various antibiotics target different aspects of bacterial physiology. Some antibiotics inhibit cell wall synthesis, some inhibit protein synthesis, and others disrupt metabolic processes or genetic material.

5. **Specific Antibiotic**: Among the antibiotics mentioned, tetracycline is known to specifically inhibit the interaction between tRNA and mRNA. It does this by binding to the ribosomal subunit, preventing tRNA from attaching to the mRNA.

6. **Conclusion**: Therefore, the correct answer to the question is tetracycline, which is option number 1.

### Final Answer:
The antibiotic that inhibits the interaction between tRNA and mRNA is **tetracycline**.
