Give the proper terms for the following statements:-
a) Techniques to alter the chemistry of genetic material to introduce these into host organisms and thus change the phenotype of the host organism.
b) Maintenance of sterile ambience in chemical engineering processes to enable growth of only the desired microbe or eukaryotic cell in large quantities for the manufacture of biotechnological products.

a) Genetic engineering b) Bioprocess engineering

The correct answer is Option (2)- (a)- Genetic engineering (b)Biopress engineering 

Biotechnology deals with techniques os using live organisms or enzymes from organisms to produce products and processes useful to mankind.

Among many,the two core techniques that enabled birth of modern biotechnology are:

Genetic Engineering- Techniques to alter the chemistry of genetic material (DNA and RNA),to induce these into host organisms and thus change the phenotype of the host organism.

b) Bioprocess  engineering: Maintenance of sterile ( microbial contamination free) ambience in chemical engineering processes to enable growth of only the desired microbe/ eukaryotic cell in large quantities for the manufacture of biotechnological products like antibiotics, vaccines, enzymes,etc.
