Options

A. red biotechnology and green biotechnology
B. classical and traditional biotechnology
C. genetics and mathematics
D. genetic engineering and maintenance of sterile environment

Answer

D

Explanation

Genetic engineering and maintenance of a sterile environment are the two core techniques that gave birth to modern biotechnology. Genetic engineering uses techniques to alter the chemistry of genetic material and exploit them, while maintenance of a sterile environment enables the growth of only the desired organisms in large quantities for the manufacture of biotechnological products.
