Agrobacterium tumefaciens used in Genetic engineering for

Options

A. DNA-mapping
B. DNA-modification
C. Gene transfer
D. DNA finger printing

Answer

**Step-by-Step Solution:**

1. **Understanding Agrobacterium tumefaciens:**
- Agrobacterium tumefaciens is a soil bacterium known for its ability to transfer genetic material to plants. It is commonly used in genetic engineering.

2. **Identifying the Options:**
- The question provides four options regarding the use of Agrobacterium tumefaciens in genetic engineering:
- A) DNA mapping
- B) DNA modification
- C) Gene transfer
- D) DNA fingerprinting

3. **Analyzing Each Option:**
- **Option A: DNA mapping** - This involves determining the nucleotide sequence of DNA. It does not relate to the function of Agrobacterium tumefaciens.
- **Option B: DNA modification** - This refers to changing the DNA sequence as per requirements. While this can be a part of genetic engineering, it is not the primary function of Agrobacterium tumefaciens.
- **Option C: Gene transfer** - This is the process where a desired gene is transferred from one organism to another. Agrobacterium tumefaciens is specifically known for its ability to transfer genes into plant cells.
- **Option D: DNA fingerprinting** - This technique is used for identifying individuals based on their DNA profiles. It is not related to the function of Agrobacterium tumefaciens.

4. **Conclusion:**
- Based on the analysis, Agrobacterium tumefaciens is primarily used for gene transfer in genetic engineering. It transfers the tumor-inducing (Ti) plasmid into the plant cells, leading to the integration of new genetic material into the plant genome.

5. **Final Answer:**
- The correct answer is **Option C: Gene transfer**.
