Answer 1

The correct option is D (a) (b) (c) (d)

(iv) (i) (ii) (iii)
Bt cotton is resistant to cotton bollworm. ADA deficiency can be treated by enzyme replacement therapy, bone marrow transplantation or gene therapy.
RNAi involves silencing of specific mRNA. Polymerase chain reaction is in-vitro amplification of DNA.
