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 |
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 |
| 1. | Agro-chemical based agriculture |
