Plasmid

Solution

Plasmids are extrachromosomal molecules of $DNA$ that replicate independently of the bacterial chromosomes. They are normally closed, circular, super coiled. They are used as a vector for cloning and genetic engineering.

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.
