Question

Regarding assertion and reason, select the correct option:

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

• A. Both the assertion and reason are true and the reason is the correct explanation for the assertion.
• B. Both the assertion and reason are true but the assertion is not the correct explanation of the reason.
• C. 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 assertion is not the correct explanation of the reason.

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.
