In gene gun method used to introduce alien DNA into host cells, microparticles of ____ metals are used.

Options

  1. ASilver
  2. BCopper
  3. CZinc
  4. DTungsten or gold

Correct answer

D. Tungsten or gold

Step-by-step solution

Micro-injection is a method where the 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.
