ii. Use of cell productivity for production of antibiotics and vaccines.
iii. Production and use of biomolecules like DNA and proteins for human welfare.
iv. Gene manipulation to develop plants and animals with desired qualities, and bacteria capable of synthesizing important molecules.
v. Use of both genetic (gene manipulation) and non-genetic (tissue culture, hybrid seed production) techniques.
