Question

The T${}_i$ plasmid, is often used for making transgenic plants. This plasmid is found in

• A. Azotobacter
• B. Rhizobium of the roots of leguminous plants
• C. Agrobacterium
• D. Yeast as a 2$\mu$m plasmid

Answer 1

Answer: (C)

Agrobacterium

A Ti- or tumour inducing plasmid is a circular plasmid present in the cells of the bacterium Agrobacterium tumefaciens and Agrobacterium rhizogenes. These bacteria use the plasmid genes to transduce its genetic material into the plants. This plasmid is used for the introduction of the desired genes into the plant cells and making them transgenic plants.

Thus, the correct answer is option C.
