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?
Answer & explanation
Correct answer: option 4
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.
