Biolistics (gene-gun) is suitable for:

1. DNA finger printing
2. Disarming pathogen vectors
3. Transformation of plant cells
4. Constructing recombinant DNA by joining with vectors

Correct answer: Transformation of plant cells

Solution

Biolistics, or the gene gun method, propels DNA-coated particles into target cells. It is especially useful for transforming plant cells because their rigid cell wall makes other DNA delivery methods less effective.
