Bacterial cell which has prophages inside them is

Options

A. Lysogenic bacteria
B. Lytic bacteria
C. Both (1) and (2)
D. None of these

Answer

To answer the question "Bacterial cell which has prophages inside them is", we can follow these steps:

### Step 1: Understand the Terms
- **Prophage**: A prophage is a viral genome that is integrated into the bacterial genome. It is a stage in the life cycle of a bacteriophage when it is dormant within the bacterial cell.
- **Lysogenic Bacteria**: These are bacteria that contain a prophage within their genome. The viral DNA is integrated into the bacterial DNA and can replicate along with it without causing immediate harm to the host.
- **Lytic Bacteria**: In contrast, lytic bacteria are those that undergo the lytic cycle, where the viral DNA does not integrate into the bacterial genome but instead replicates independently, leading to the destruction (lysis) of the bacterial cell.

### Step 2: Analyze the Options
- **Lysogenic Bacteria**: As explained, these bacteria have prophages integrated into their genome.
- **Lytic Bacteria**: These do not have prophages; they produce new viral particles and cause the bacterial cell to lyse.
- **Both 1 and 2**: This option implies that both types of bacteria can have prophages, which is incorrect.
- **None of these**: This option would suggest that neither type of bacteria has prophages, which is also incorrect.

### Step 3: Conclusion
Based on the definitions and characteristics of lysogenic and lytic bacteria, the correct answer is that the bacterial cell which has prophages inside them is **lysogenic bacteria**.

### Final Answer
**Lysogenic bacteria**
