Read the following statements and choose the correct option: 1. In a method known as biolistics, recombinant DNA is directly injected into the nucleus of an animal cell. 2. 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 micro-injection 3. A method uses ‘disarmed pathogen’ vectors, which when allowed to infect the

Options

  1. ABoth 1 and 2 are correct
  2. BBoth 1 and 2 are incorrect
  3. CBoth 3 and 5 are correct
  4. DOnly 4 is incorrect

Correct answer

C. Both 3 and 5 are correct

Step-by-step solution

This is not the only way to introduce alien DNA into host cells. 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.
