State how has Agrobacterium tumefaciens been made a useful cloning vector to transfer DNA to plant cells.

How has Agrobacterium tumefaciens been suitably modified to act as a cloning vector?

Why is Agrobacterium tumefaciens a good cloning vector ? Explain.

Why is Agrobacterium tumefaciens a good cloning vector ? Explain.

Agrobacterium tumefaciens is most widely used for gene transfer bacause of

Read the following statement and choose the correct option: I. Agrobacterium tumefaciencs, a pathogen of several monocot plants, is able to deliver a piece of DNA known as "T-DNA". II. The tumor inducing (Ti) plasmid of Agrobacterium tumefaciens has been modified into a cloning vector, which is more pathogenic to the plants.

Assertion : Agrobacterium tumefaciencs causes crown gall tumor in plants. Reason : E.coli can't transfer DNA in plants.

How does Agrobacterium tumifaciens act as a suitable vector in the biotechnological experiments ? Site an example where it has been successfully used as a vector.

What modification is done on the Ti-plasmid of Agrobacterium tumefaciens to convert it into cloning vector?

What is the source of the Ti (Tumor inducing) plasmid which is modified and used as a cloning vecotr to deliver the desirable genes into plant cells?

(a) Mention the cause and the body system affected by ADA deficiency in humans. (b) Name the vector used for transferring ADA-DNA into the recipient cells in humans. Name the recipient cells.
