For transformation, microparticles coated with DNA to be bombarded with gene gun are made up of

Options

  1. Asilver or platinum
  2. Bplatinum or zinc
  3. Csilicon or platinum
  4. Dgold or tungsten

Correct answer

D. gold or tungsten

Step-by-step solution

Biolistics or gene gun is a direct or vectorless way used to introduce alien DNA into host cells. In this method of gene transfer, high velocity micro-particles of gold or tungsten, coated with DNA are bombarded on the plant cells.
