| Techniques/Instruments | Usage |
| Bioreactor | It is used for the large scale production of desired products |
| Electrophoresis | Separation of DNA fragments based on molecular size. Large fragments are found near the cathode, while smaller fragments are found near the anode. |
| PCR | It is also called amplifier as it is responsible for Amplification of nucleic acids. |
| ELISA | Detection of the pathogen, based on antigen-antibody reaction. It is one of the confirmatory tests for detection of HIV. |

The blue and white selectable markers have been developed which differentiate recombinant colonies from non-recombinant colonies on the basis of their ability to produce colour in the presence of a chromogenic substrate. Given below are two statements about this method: Statement I : The blue coloured colonies have DNA insert in the plasmid and they are identified as recombinant colonies. Statement II : The colonies without blue colour have DNA insert in the plasmid and are identified as recombinant colonies. In the light of the above statements, choose the most appropriate answer from the options given below:
