Question:
The Ti plasmid of Agrobacterium tumefaciens contains a transposon called:
The Ti plasmid of Agrobacterium tumefaciens contains a transposon called:
Show Hint
The Ti plasmid is engineered such that the T-DNA region can be replaced with any desired foreign gene, which can then be inserted into the host plant’s genome. The T-DNA is transferred to plant cells, where the introduced gene is expressed, thus allowing for genetic modification.

- T DNA
- R DNA
- cDNA
- A DNA
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The Ti (tumor-inducing) plasmid of Agrobacterium tumefaciens contains a segment of DNA called T DNA (Transfer DNA), which is transferred from the bacteria to the plant genome during infection. The T-DNA is a specific DNA that contains the genes required for tumor growth in plants. Options R, cDNA and A DNA are not related to the Ti plasmid.
