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

Dolly sheep was obtained by:
 

Minute quantities of hormones & steroids is detected by:
1.  Electrophoresis
2.  Radioimmunoassay
3.  Electroencephalogram
4.  Fractional analysis

Triticale is obtained by crossing wheat with:
1.  Oat
2.  Barley
3.  Maize
4.  Rye

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

The introduction of food plants developed by genetic engineering is not desirable because:
 

Cellular totipotency is demonstrated by:

2. All plant cells
3. All eukaryotic cells
4. Only bacterial cells

1. Alkaline phosphatase

2. Catalase

3. DNA probe

4. RNase
