Why is Agrobacterium tumefaciens a good cloning vector ? Explain.

Explanation

**Step-by-Step Solution:**

1. **Introduction to Agrobacterium tumefaciens:**
Agrobacterium tumefaciens is a soil bacterium that is known for its ability to transfer DNA to plants, which makes it a valuable tool in plant biotechnology.

2. **Tumor Induction:**
This bacterium causes crown gall disease in plants by transferring a segment of its DNA (known as T-DNA) from its tumor-inducing plasmid (Ti-plasmid) into the plant cells. This T-DNA integrates into the plant's genome, leading to uncontrolled growth and tumor formation.
