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

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explananation of the assertion
C. If the assertion is true but the reasons is false
D. If both the assertion and reason are false

Answer

B

Explanation

Although thousands of proteins have been characterized in prokaruotes and eukaryotes, only few become commercially imortant. This is due to the high cost of isolating and purifying enzymes in sufficuient quantities. Through recombinant DNA techonology, a protein can be obtined in aboundant quantity the objectieves of protein engineering are to create superior objective of protien engineering are to high value specfice chiemincal and to produce enzymes produce enzymes for large sacel sue.
