Question

Genetic engineering is used in

• A. Gene therapy
• B. Vaccine production
• C. Obtaining transgenic plants
• D. All of the above

Answer 1

The correct option is D All of the above

Genetic engineering has applications in medicine, research, industry and agriculture and can be used on a wide range of plants, animals and microorganisms. In medicine, genetic engineering has been used to mass-produce insulin, human growth hormones, human albumin, monoclonal antibodies, anti haemophilic factors, vaccines, and many other drugs. In research, organisms are genetically engineered to discover the functions of certain genes. Industrial applications include transforming microorganisms such as bacteria or yeast or insect mammalian cells with a gene coding for a useful protein. Mass quantities of the protein can be produced by growing the transformed organism in bioreactors using fermentation, then purifying the protein. Genetic engineering is also used in agriculture to create genetically-modified crops or genetically-modified organisms

So, the correct answer is 'All of the above'
