Assertion : Agrobacterium tumefaciens is popular in genetic engineering because this bacterium is associated with the roots of all cereal and pulse crops.

Reason : A gene incorporated in the bacterial chromosomal genome gets automatically transferred to the crop with which the bacterium is associated.

Assertion : The uptake of DNA during transformation is an active, energy requiring process.

Reason : Transformation occurs in only those bacteria, which possess the enzymatic machinery involved in the active uptake and recombination.

Linking of antibiotic resistance gene with the plasmid vector became possible with

The process of separation and purification of expressed protein before marketing is called

What is the criterion for $\mathrm{DNA}$ fragments movement on agarose gel during gel electrophoresis?

A gene whose expression helps to identify transformed cell is known as

The DNA fragments separated on agarose gel can be visualised after staining with:

Which of the following is commonly used as a vector for introducing a $\mathrm{DNA}$ fragment in human Iymphocytes?
