Polyethylene glycol can help in the uptake of foreign DNA into the host cell, this type of gene transfer is called as:

Options

A. Electroporation
B. Microinjection
C. Particle gun
D. Chemical mediated genetic transformation

Answer

To solve the question regarding the role of polyethylene glycol in the uptake of foreign DNA into host cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Role of Polyethylene Glycol (PEG)**:
- Polyethylene glycol is a chemical compound that can facilitate the uptake of foreign DNA by making the cell membrane more permeable.

2. **Identifying the Options**:
- The question provides four options:
1. Electroporation
2. Microinjection
3. Particle gun
4. Chemical mediated genetic transformation

3. **Evaluating Each Option**:
- **Electroporation**: This method involves applying an electric field to increase cell permeability. Since PEG is not an electric method, this option is incorrect.
- **Microinjection**: This technique uses a glass micropipette to inject substances directly into cells. It does not involve PEG, making this option incorrect.
- **Particle Gun**: This method uses high-velocity microprojectiles to deliver DNA into cells. PEG is not used in this method, so this option is also incorrect.
- **Chemical Mediated Genetic Transformation**: This method involves using chemicals (like PEG) to facilitate the uptake of DNA by cells. Since PEG is specifically mentioned as aiding in this process, this option is correct.

4. **Conclusion**:
- The correct answer to the question is **Chemical mediated genetic transformation**.

### Final Answer:
The type of gene transfer facilitated by polyethylene glycol for the uptake of foreign DNA into the host cell is called **Chemical mediated genetic transformation**.
