An example of gene therapy is

Options

  1. Aproduction of injectable hepatitis B vaccine
  2. Bproduction of vaccines in food crops like potatoes which can be eaten
  3. Cintroduction of gene for adenosine deaminase in persons suffering from Severe Combined Immuno Deficiency (SCID
  4. Dproduction of test tube babies by artificial insemination and implantation of fertilised eggs.

Correct answer

C. introduction of gene for adenosine deaminase in persons suffering from Severe Combined Immuno Deficiency (SCID
