Question

Extensively used tool in genetic engineering of crop plants is _________________.

• A. Agrobacterium mediation
• B. Protoplast fusion
• C. Transposons
• D. Microinjection

Answer 1

The correct option is A Agrobacterium mediation

Transposons are basically jumping genes. Protoplast fusion is a technique of creating hybrids, the mating of one species protoplast and other species protoplast. While microinjection is a method of injecting our interest of DNA directly into the host. We can achieve transformation by microinjection too but Agrobacterium-mediated transformation is most commonly used. Agrobacterium tumefaciens is a naturally occurring soil bacterium causing crown gall disease and has the ability to introduce new genetic material into the plant cell.

Hence, the correct answer is 'Agrobacterium-mediation'.
