Alpha-1-antitrypsin was produced in a transgenic sheep, Tracy. This enzyme is used in the treatment of:
1. | Emphysema | 2. | Rheumatoid arthritis |
3. | Ovarian cancer | 4. | Pancreatitis |
Why does the bacterium Bacillus thuringiensis not affected by the toxins produced by it that can kill arthropods?
1. | The toxin inactivated by proteins in the bacterial cells. |
2. | The bacterial cell does not have organelles and thus it is harmless. |
3. | It is produced as a pro-toxin by the bacterium. |
4. | The protein needs post-transcriptional modification possible only in eukaryotic cells. |
GM crops have been modified with various traits. Golden rice has been developed by the International Rice Research Institute for:
1. | Improved shelf life | 2. | Disease resistance |
3. | Herbicide resistance | 4. | Improved nutritional value |
Transgenic animals used to test the safety of polio vaccine are:
1. | Mice | 2. | Monkeys |
3. | Rabbits | 4. | Pigs |
A possible permanent cure for SCID can be:
1. | Enzyme replacement therapy, in which functional ADA is given to the patient by injections. |
2. | Bone marrow transplantation. |
3. | A functional ADA cDNA (using a retroviral vector) introduced into lymphocytes. |
4. | Gene isolated from marrow cells producing ADA is introduced into cells at early embryonic stages. |
Transgenic mice are being used to test the safety of polio vaccine. They could replace the use of:
1. | Monkeys | 2. | Rabbits |
3. | Fowl | 4. | Frogs |
Nematode [Meloidogyne incognita] specific genes were transferred to tobacco plant using:
1. | Retroviral vectors | 2. | Gene gun |
3. | Agrobacterium mediation | 4. | Micro-injection |
Corn borer can be controlled by the proteins encoded by Bacillus thuringiensis gene:
1. | cryIAb | 2. | cryIAc |
3. | cryIIAb | 4. | cryIIIAc |
The name Genetic Engineering Approval Committee [GEAC] has been changed to:
1. | Genetic Engineering Advisory Committee |
2. | Genetic Engineering Appellate Committee |
3. | Genetic Engineering Appraisal Committee |
4. | Genetic Engineering Arbitration Committee |
Antisense technology:
1. | selectively blocks the expression of a gene. |
2. | combines genetic material from different species. |
3. | combines organelles and cells. |
4. | alters or transfers cells. |
