Q. No.Which of the following is not a critical research area of biotechnology
| 1. | Providing a best catalyst in the form of improved organism usually microbe or pure enzyme |
| 2. | Creating optimal conditions through engineering for a catalyst to act |
| 3. | Downstream processing technologies to purify the protein or organic compound |
| 4. | Upstream processing of all the activated antibodies and plasminogens in plant body |
The method of producing thousand of plantlets through culture is called:
1. Micropropagation
2. Clonal selection
3. Hardening
4. Acclimatization
It is possible to raise a large number of plantlets through micro-propagation because of the presence of which of the following properties in plants?
1. Cellular totipotency
2. Phenotypic plasticity
3. Closed development
4. Determined growth
Totipotency refers to
| 1. | capacity to generate genetically identical plants. |
| 2. | capacity to generate a whole plant from any plant cell / explant. |
| 3. | capacity to generate hybrid protoplasts. |
| 4. | recovery of healthy plants from diseased plants. |
Genetically identical plants produced by micropropagation are called
1. Explants
2. Somaclones
3. Somatic hybrids
4. Cybrids
Transgenic plants are the ones
| 1. | Grown in artificial medium after hybridization in the field |
| 2. | Produced by a somatic embryo in artificial medium |
| 3. | Generated by introducing foreign DNA in to a cell and generating a plant from that cell |
| 4. | Produced after protoplast fusion in artificial medium |
