Question

Which of the following best describes vector-dependent gene transfer?

पर्याय

• Cross-pollination between sexually compatible plant species

• Chemical mutagenesis of plant genes using alkylating agents

• Spontaneous uptake of DNA by plant cells from the environment

• Using vectors to deliver foreign genes efficiently into plant cells

Answer 1

Vector-dependent gene transfer uses vectors to deliver foreign genes efficiently into plant cells. Common vectors include Agrobacterium tumefaciens with its Ti plasmid and various plant viruses that serve as delivery vehicles for genetic material.
