MCQs on Transgenic Animals

Transgenic animals are:

• Animals with improved nutritional value

• Animals whose genome has been altered by introducing a foreign gene

• Animals selected through natural breeding

• Animals that are resistant to pesticides

Alpha-1-antitrypsin produced by transgenic sheep is used for the treatment of:

• Diabetes

• Emphysema

• Cancer

• Hemophilia

Which bioactive product from transgenic cows improves the nutritional quality of milk?

• Insulin

• Alpha-lactalbumin

• Growth hormone

• Hemoglobin

Transgenic animals are used for vaccine safety testing because:

• They produce vaccines in milk

• They can be used to test efficacy and side effects before human use

• They reduce the cost of vaccine production

• They prevent disease naturally

Which of the following is an example of a therapeutic protein produced by transgenic animals?

• Vitamin D

• Human clotting factor VIII

• Iron

• Collagen

The role of GEAC in India is to:

• Develop vaccines

• Approve large-scale use of genetically modified organisms

• Produce bioactive products

• Conduct animal experiments

Which of the following diseases is studied using transgenic mice models?

• Hypertension

• Alzheimer’s disease

• Common cold

• Malaria

The main advantage of using transgenic animals as bioreactors is:

• They reduce ethical issues

• They produce proteins that are biologically active and correctly folded

• They replace natural ecosystems

• They do not require regulation

Which of the following is NOT an application of transgenic animals?

• Production of bioactive products

• Chemical safety testing

• Increasing biodiversity

• Study of human diseases

The ethical concern in using transgenic animals is mainly due to:

• Low cost of production

• Pain and suffering caused to animals

• High efficiency of protein synthesis

• Reduced drug development time
