Write the stpes you would suggest to be undertaken to obtain a foreign-gene-product.

Explanation

Step-I: When you inset a piece of DNA into cloning vector and transfer into a bacterial plant or animal cell, the alien DNA gets multiplied.
Step II: After having cloned the gene of interest and having optimised the conditions to induce the expression of the target protien, one has to consider producing it on a large scale.
Step III. The cultures may be ued for extracting the desired protein and then purifying it by using different separation techniques.
iv) The cells can also multiplied in a continuous culture system. The used medium is drained out from one side while fresh medium is added from the other to maintain the cells in their physiologically most active log exponential phase.
