Insertion of prokaryotic DNA into a eukaryotic cell without human intervenation is :

Options

A. impossible
B. seen in bacteriophages
C. naturally observed in nature
D. leads to production of double stranded RNA making translation impossible

Answer

To solve the question regarding the insertion of prokaryotic DNA into a eukaryotic cell without human intervention, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the natural process through which prokaryotic DNA can be inserted into a eukaryotic cell without any human intervention.

2. **Analyzing the Options**:
- **Option A**: Claims that this process is impossible. This is incorrect because there are natural mechanisms that allow for the transfer of DNA.
- **Option B**: Refers to bacteriophages, which are viruses that infect bacteria. This option is also incorrect as it pertains to the transfer of viral DNA, not prokaryotic DNA into eukaryotic cells.
- **Option C**: This option is not explicitly mentioned in the transcript, but it is implied that it could relate to natural processes that allow for DNA transfer.
- **Option D**: States that the insertion leads to the production of double-stranded RNA, making translation impossible. This is incorrect as it relates to RNA interference, not the direct insertion of prokaryotic DNA into eukaryotic cells.

3. **Identifying the Correct Process**: The correct process for the insertion of prokaryotic DNA into a eukaryotic cell without human intervention is through natural mechanisms such as transformation. Transformation is a process where bacteria can take up foreign DNA from their environment, which can include DNA from eukaryotic cells.

4. **Conclusion**: Based on the analysis, the correct answer to the question is that the insertion of prokaryotic DNA into a eukaryotic cell without human intervention can occur naturally through the process of transformation.

### Final Answer:
The correct answer is **Option C** (implied as the correct answer in the context of the transcript), as it relates to the natural process of transformation.
