Assertion : In a chemical engineering process, it is necessary to prepare sterile ambience.
Reason : Sterile ambience inhibits the growth of undesirable microbes during manufacture of product like antibiotics, vaccines and enzymes.

Options

A. a) Both assertion and reason are true and reason is correct explanation of assertion.
B. b) Both assertion and reason are true but reason is not correct explanation for assertion.
C. c) Assertion is true but reason is false.
D. d) Assertion is false but reason is true.

Answer

A

Explanation

During sterilisation, the equipments, etc, are made free of any microoganism before the addition of desired microbe or cell. Now, this desired organism does not get any competition from other organisms and expresses all its characters and grows effectively. Hence, sterilisation enables growth of only the desired microbe. It is also evident that along with genetic engineering, sterilisaton is also essential for sussessful biotechnological experiments.
