Q. No.The European Federation of Biotechnology [EFB] defines biotechnology as:
| 1. | The use of living cells and bacteria in industrial and scientific processes. |
| 2. | The integration of natural sciences and organisms, cells, parts thereof, and molecular analogues for products and services. |
| 3. | The use of biology to solve problems and make useful products. |
| 4. | The use of biology to develop new products, methods and organisms intended to improve human health and society. |

Two core techniques that enabled birth of modern biotechnology are:
| A: | Techniques to alter the chemistry of genetic material, to introduce these into host organisms and thus change the phenotype of the host organism. |
| B: | Maintenance of sterile ambience in chemical engineering process to enable growth of only the desired microbes/eukaryotic cell in large quantities for the manufacture of biotechnological products. |
| 1. | A is called as Genetic Engineering and B is called as Biophysical engineering. |
| 2. | A is called as Genomics and B is called as Bioprocess engineering. |
| 3. | A is called as Genetic Engineering and B is called as Bioprocess engineering. |
| 4. | A is called as Genomics and B is called as Biophysical engineering. |
