In a method of introducing alien DNA into competent host cells, the cells are bombarded with high velocity micro-particles of gold or tungsten coated with DNA. Identify the name of this method and the specific type of host cell it is primarily suitable for.

Options

  1. ABiolistics, Plant cells
  2. BMicro-injection, Animal cells
  3. CBiolistics, Animal cells
  4. DDisarmed retrovirus, Plant cells

Correct answer

A. Biolistics, Plant cells

Step-by-step solution

The method described is biolistics or the gene gun method, where cells are bombarded with high velocity micro-particles of gold or tungsten coated with DNA. This method is primarily suitable for introducing recombinant DNA into plant cells. Micro-injection is a different method where recombinant DNA is directly injected into the nucleus of an animal cell using a micropipette. Disarmed retroviruses are used as vectors to deliver desirable genes into animal cells, not plant cells. Answer: Biolistics, Plant cells
