Question

Assertion :Extraction and purification of enzymes is laborious and expensive. Reason: Protein engineering can be used to produce enzymes at large scale.

• A. Both the assertion and the reason are true and the reason is a correct explanation of the assertion.
• B. Both the assertion and reason are true but the reason is not a correct explanation of the assertion.
• C. The assertion is true but the reason is false.
• D. Both the assertion and reason are false.

Answer 1

The correct option is B Both the assertion and reason are true but the reason is not a correct explanation of the assertion.

Although thousands of proteins have been characterized in prokaryotes and eukaryotes, only few became commercially important. This is due to the high cost of isolating and purifying enzymes in sufficient quantities. Through recombinant DNA technology, a protein can be obtained in abundant quantity the objectives of protein engineering are to create superior enzymes to catalyze the production of high-value specific chemicals and to produce enzymes for large-scale use.
