Q. No.Golden rice is a genetically modified crop plant where the incorporated gene is meant for the biosynthesis of:
| 1. | Vitamin-B | 2. | Vitamin-C |
| 3. | Omega 3 | 4. | Vitamin-A |
Consumption of which one of the following foods can prevent the kind of blindness associated with vitamin-A deficiency?
| 1. | Flaver savr tomato | 2. | Canolla |
| 3. | Golden rice | 4. | Bt-brinjal |
An improved variety of transgenic basmati rice:
| 1. | does not require chemical fertilizers and growth hormones |
| 2. | gives high yield and is rich in vitamin-A |
| 3. | is completely resistant to all insect pests and diseases of paddy |
| 4. | gives high yield but has no characteristic aroma |
Transgenic plants are:
| 1. | produced by a somatic embryo in artificial medium |
| 2. | generated by introducing foreign DNA into a cell and regenerating a plant from that cell |
| 3. | Produced after protoplast fusion in artificial medium |
| 4. | grown in artificial medium after hybridization in the field |
| 1. | Flavr savr tomatoes |
| 2. | Starlink maize |
| 3. | Bt soybean |
| 4. | Golden rice |
| 1. | eliminate weeds from the field without the use of manual layout |
| 2. | eliminate weeds from the field without the use of herbicides |
| 3. | encourage eco-friendly herbicides |
| 4. | reduce herbicide accumulation in food particles for health safety |
Golden rice is a promising transgenic crop. When released for cultivation, it will help in:
1. alleviation of vitamin-A deficiency
2. pest resistance
3. herbicide tolerance
4. producing a petrol-like fuel from rice
Microbes found to be very useful in genetic engineering are:
1. Escherichia coli and Agrobacterium tumefaciens
2. Vibrio cholerae and a tailed bacteriophage
3. Diplococcus sp. and Pseudomonas sp.
4. Crown gall bacterium and caenorhabditis elegans
