Question

The plasmid of Agrobacterium tumefaciens that is now modified as a cloning vector is ______.

पर्याय

• Pi-plasmid

• cosmid

• Ti-plasmid

• None of these

Answer 1

The plasmid of Agrobacterium tumefaciens that is now modified as a cloning vector is Ti-plasmid.

Explanation:

Plant pathogen Agrobacterium tumefaciens works best as a plant genetic engineer. In plants, it results in the development of crown gall. Ti, a plasmid that causes tumours, is a valuable cloning vector in plants. It can be altered with additional DNA, and the plasmid inserts a DNA fragment that changes healthy plant cells into cancerous ones. The insertion of the Ti plasmid into a plant enables it to build its own nutritional machinery since it contains genes for the synthesis of auxin and the hormone cytokinin.
