Interferon :

Options

A. Kills the virus in virus infected cell
B. Kills the virus and destroy cancerous cell
C. Stimulates the T.I.P. (Translation Inhibiting protein)
D. Antibacterial

Answer

### Step-by-Step Solution:

1. **Definition of Interferon**:
- Interferon is an antiviral protein produced by cells in response to viral infections. It is part of the body's immune response.

2. **Function of Interferon**:
- When a cell is infected by a virus, it releases interferons. These proteins act on neighboring uninfected cells, preparing them to resist viral infection.

3. **Mechanism of Action**:
- Interferons stimulate the production of translation-inhibiting proteins (TIP) in adjacent cells. These proteins inhibit the virus's ability to translate its own proteins, effectively preventing the virus from replicating.

4. **Evaluating Options**:
- **Option A**: States that interferon kills the virus in the virus-infected cell. This is incorrect because interferon does not directly kill viruses.
- **Option B**: Claims that interferon kills the virus and destroys cancerous cells. This is also incorrect as interferon does not have a direct role in killing cancer cells.
- **Option C**: States that interferon stimulates TIP (Translation Inhibiting Protein). This is correct and aligns with the function of interferon.
- **Option D**: Claims that interferon is antibacterial. This is incorrect since interferon is specifically antiviral.

5. **Conclusion**:
- The most appropriate answer is Option C, as it accurately describes the role of interferon in stimulating translation-inhibiting proteins.
