Transgenic Animals - Uses and Ethics - Unsolved Practice Set

Q1. Transgenic animals are defined as animals that:

1. Have had their genome manipulated to possess an additional (foreign) gene or altered genetic material
2. Are bred purely through natural, unmodified mating
3. Have never been studied scientifically
4. Are always sterile and unable to reproduce

Q2. One important scientific use of transgenic animals is to:

1. Study the role of specific genes by observing how their absence or presence affects normal physiology and development
2. Eliminate the need for any animal research entirely
3. Replace all human clinical trials
4. Reduce scientific understanding of gene function

Q3. Transgenic animals have been used to produce certain biological products, such as a specific human protein secreted in the animal's:

1. Blood only, with no other application
2. Milk, from which the protein can then be extracted and purified
3. Fur
4. Bones only

Q4. Transgenic mice are commonly used in research as models to study:

1. Only healthy, unmodified physiological processes
2. Human diseases, by introducing specific genes associated with a particular condition
3. Only plant diseases
4. Weather patterns

Q5. A significant ethical concern associated with the use of transgenic animals relates to:

1. The complete absence of any scientific benefit
2. Animal welfare and the moral implications of genetically modifying living animals for human purposes
3. Their total unavailability for any kind of research
4. Their guaranteed harmlessness in every situation
