On a plate that has ampicillin and a chromogenic substrate, a student sees blue and white colonies. The vector has ampR and a lacZ gene with the cloning site inside it. Which colonies should she pick to find the cloned gene?
The blue colonies, because the enzyme works
The blue colonies, because they carry ampR
The white colonies, because the insert broke lacZ
The white colonies, because they have no plasmid
