Read the statements about gene gun method.

I. The gene gun method is also referred to as the biolistic technique.

II. In this method, cells are bombarded with high-velocity microparticles coated with DNA in plants, with gold or tungsten being commonly used.

III. Suitable for plants

Which of the statements given above are correct?

I, II and III

The correct answer is Option (4) – I, II and III

 In a method known as micro-injection, recombinant DNA is directly injected into the nucleus of an animal cell.

In another method, suitable for plants, cells are bombarded with high velocity micro-particles of gold or tungsten coated with DNA in a method known as biolistics or gene gun.

And the last method uses ‘disarmed pathogen’ vectors, which when allowed to infect the cell, transfer the recombinant DNA into the host.
