Correct answer: B. Genetic engineering
- A. Immunization
- B. Genetic engineering
- C. Tissue culture
- D. Biotechnology.
Explanation
Genetic engineering is the experimental manipulation of genetic material, especially for industrial or medical uses. It encompasses the techniques of gene cloning, the modification of DNA by changes in sequence arrangement or deletion, and the introduction of novel genes into cells and organisms. It may prove possible to advantageously modify the genes of farmed animals, to correct genetic deficiencies of the human by inserting novel genes. This can be done by breakage of a DNA molecule at two desired places into another DNA molecule of the desired animal.

About Biotechnology
Biotechnology in health care applies biological organisms, cells or enzymes to diagnose and treat disease. The subject includes recombinant DNA, genetically engineered insulin, vaccines, antibiotics, monoclonal antibodies, gene therapy and techniques such as polymerase chain reaction, while distinguishing therapeutic applications from agricultural and industrial biotechnology.
