Which of the following is true for Golden rice?
| 1. | It has yellow grains, because of gene introduced from a primitive variety of rice |
| 2. | It is Vitamin A enriched, with a gene from daffodil |
| 3. | It is pest resistant, with a gene from Bacillus thuringiensis |
| 4. | It is drought tolerant, developed using Agrobacterium vector |
Bacillus thuringiensis (Bt) strains have been used for designing novel:
1. Bio metallurgical technique
2. Bio mineralization processes
4. Bio insecticidal plants
4. Bio fertilizers
The protein a -1 antitrypsin is used to treat which of the following diseases?
| 1. | Cancer |
| 2. | Rheumatoid arthritis |
| 3. | Emphysema |
| 4. | ADA deficiency disease in children |
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 |
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
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 |
