A plasmid vector has a gene for erythromycin resistance (Ery") and a gene for ampicillin resistance (Amp"). The Ery gene is cut
NikAS [45]

Answer:

Amp resistant phenotypes

Explanation:

Insertion of the desired gene sequence within the sequence of an antibiotic resistance gene makes the transformed cells to lose the resistance against that particular antibiotic. To create a recombinant plasmid vector, the sequence of the gene for erythromycin resistance was cut with the restriction enzyme. This would cause a loss of resistance against erythromycin in the transformed cells. Since the ampicillin resistance gene was intact, the transformed gene would exhibit resistance against ampicillin. Therefore, the transformed cells would be ampicillin-resistant and erythromycin sensitive.
