well u r asking engineering in pharmaceutical and medicines well the factory make those stuff need machines and calculation to build that stuff and need maintenance of those stuff.
and genetic engineering:-
Genetic engineering is a laboratory technique used by scientists to change the DNA of living organisms.

DNA is the blueprint for the individuality of an organism. The organism relies upon the information stored in its DNA for the management of every biochemical process. The life, growth and unique features of the organism depend on its DNA. The segments of DNA which have been associated with specific features or functions of an organism are called genes.

good luck
