Vedclass · Answer

(C) The plasmid contains the $\beta$-galactosidase gene,which is responsible for the production of the enzyme $\beta$-galactosidase. When a foreign $	ext{DNA}$ fragment is inserted at the $	ext{EcoRI}$ site,which is located within the $\beta$-galactosidase gene,it leads to the insertional inactivation of the gene. As a result,the enzyme $\beta$-galactosidase is not produced. In the presence of a chromogenic substrate,non-recombinant colonies (containing the functional gene) produce a blue color,whereas recombinant colonies (where the gene is inactivated) appear white. Therefore,white color colonies are selected to identify the recombinants.

In the above represented plasmid,an alien piece of $\text{DNA}$ is inserted at the $\text{EcoRI}$ site. Which of the following strategies will be chosen to select the recombinant colonies?
