Answer 1

Ans: (3) (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)

Sol. The correct answer is option (3) as (a) in column i.e. bioreactor matches with (ii) production of large quantities of products.

Electrophoresis is used for separation of DNA fragments so, (b) matches with (i)

PCR is polymerase chain reaction that is employed for amplification of nucleic acids, so (c) matches with (iv).

ELISA stands for enzyme linked immunosorbent assay and it is used for detection of pathogen based on antigenantibody interaction, so (d) matches with (iii).
