Q. No.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
regenerating a plant from that cell
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 |
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 |
Which one of the following is commonly used in the transfer of foreign DNA into crop plants?
1. Trichoderma harzianum
2. Meloidogyne incognita
3. Agro bacterium tumefaciens
4. Penicillium expansum
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 |
Which of the following Bt crops is being grown in India by the farmers?
| 1. | Cotton | 2. | Brinjal |
| 3. | Soybean | 4. | Maize |
The first human hormone produced by recombinant DNA technology is:
1. Insulin
2. Estrogen
3. Thyroxin
4. Progesterone
Why does Bt toxin not kill Bacillus thuringiensis?
1. The bacillus keeps proteins in inclusions
2. The toxin exists in the bacillus as a pro-toxin
3. The bacillus protects its genetic material by methylation
4. The bacillus has a tough cell wall of peptidoglycan
Cotton plants can be protected from corn borer by the proteins coded by:
1. cryIAc 2. cryIIAb
3. cryIAb 4. cryIAd
