Match the following techniques or instruments with their usage:

(a) Bioreactor (i) Separation of DNA fragments
(b) Electrophoresis (ii) Production of large quantities of products
(c) PCR (iii) Detection of pathogen, based on antigen-antibody reaction
(d) ELISA (iv) Amplification of nucleic acids

Select the correct option from following:

  1. (a)-(iii), (b)-(ii), (c)-(iv), (d)-(i)
  2. (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
  3. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
  4. (a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)

Solution

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.
