Using recombiant DNA technology, genes from a donor cell can be inserted into a bacterium for DNA replication and protein synthesis. The kind of cells that can be used as gene donors in this technology are

Options

A. bacteria only
B. either yeast or bacteria only
C. eukaryotic cells only
D. any kind of cell

Answer

To answer the question regarding the types of cells that can be used as gene donors in recombinant DNA technology, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Recombinant DNA Technology**:
- Recombinant DNA technology involves the insertion of genes from one organism into another organism. This allows for the replication of the inserted DNA and the synthesis of proteins encoded by that DNA.

2. **Identifying Potential Gene Donors**:
- Gene donors can be from various sources. Commonly, they include:
- Bacteria
- Yeast
- Eukaryotic cells (which include plant and animal cells)

3. **Evaluating the Options**:
- The options provided are:
- A) Bacteria only
- B) Either yeast or bacteria
- C) Eukaryotic cells only
- D) Any kind of cell
- We need to analyze each option based on our understanding of potential gene donors.

4. **Analyzing Each Option**:
- **Option A (Bacteria only)**: Incorrect, as it excludes yeast and eukaryotic cells.
- **Option B (Either yeast or bacteria)**: Incorrect, as it also excludes eukaryotic cells.
- **Option C (Eukaryotic cells only)**: Incorrect, as it excludes bacteria and yeast.
- **Option D (Any kind of cell)**: Correct, as it includes bacteria, yeast, and eukaryotic cells.

5. **Conclusion**:
- The correct answer is **D) Any kind of cell**, as recombinant DNA technology can utilize genes from a wide variety of organisms, including bacteria, yeast, and eukaryotic cells.
