Solution
The correct option is B Both the assertion and reason are true but the reason is not the correct explanation of the assertion.
Although thousands of proteins have been characterized in prokaryotes and eukaryotes, only few have became commercially important. This is due to the high cost of isolation and purification of enzymes in sufficient quantities. Through recombinant DNA technology, a protein can be obtained in abundant quantity, the objectives to protein engineering are to create superior enzymes to catalyse production to high specific chemicals and to produce enzymes for large scale use.
