How are transformed bacteria that contain a plasmid with an inserted foreign gene identi?ed?

What will be an ideal response?


The plasmids used in this experiment also contain the LacZ gene, which activates ?-galactosidase. This enzyme cleaves the X-gal, which is also present in the media. The products of this reaction, in the presence of inducer (IPTG), give rise to blue-colored bacterial colonies.
