Vedclass · Answer

(B) The plasmid $pBR322$ contains two antibiotic resistance genes: $amp^R$ (ampicillin resistance) and $tet^R$ (tetracycline resistance).The $Pst \, I$ restriction site is located within the $amp^R$ gene.When foreign $DNA$ is inserted at the $Pst \, I$ site,the $amp^R$ gene undergoes insertional inactivation,meaning it becomes non-functional.As a result,the bacteria containing this recombinant plasmid will lose their resistance to ampicillin but will retain their resistance to tetracycline.Therefore,the bacteria will grow in a tetracycline-containing medium but will fail to grow in an ampicillin-containing medium.

If foreign $DNA$ is inserted into $pBR322$ at the $Pst \, I$ site and this plasmid is introduced into bacteria,then:
