Solution:

During sterilisation, the equipments, etc., are made free of any microorganisms 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, sterilisation is also essential for successful biotechnological experiments.
