The introduction of food plants developed by genetic engineering is not desirable because:
1. | Economy of developing countries may suffer |
2. | These products are less tasty as compared to the already existing products |
3. | This method is costly |
4. | There is a danger of coming viruses, allergens, and toxins with introduced crop |
First cloned animal:
1. Dolly sheep
2. Polly sheep
3. Molly sheep
4. Dog
ELISA is used to detect viruses where the key reagent is:
1. Alkaline phosphatase
2. Catalase
3. DNA probe
4. RNase
Dolly sheep was obtained by:
