First transgenic plant:
1. Potato
2. Tomato
3. Tobacco
4. Maize

1. | Cloning the udder cell (somatic cell) fused with unnucleated oocyte |
2. | Cloning of gametes |
3. | Tissue culture |
4. | None |
Minute quantities of hormones & steroids is detected by:
1. Electrophoresis
2. Radioimmunoassay
3. Electroencephalogram
4. Fractional analysis
E. coli is used in the production of:
1. Rifampicin
2. LH
3. Ecdyson
4. Interferon

What is the reason for the formation of embryoids from pollen grain in tissue culture medium?
1. Cellular totipotency
2. Organogenesis
3. Double fertilization

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 |
Cellular totipotency is demonstrated by:
1. Only gymnosperm cells
2. All plant cells
3. All eukaryotic cells
4. Only bacterial cells
ELISA is used to detect viruses where the key reagent is:
1. Alkaline phosphatase
2. Catalase
3. DNA probe
4. RNase
