Text Solution
Verified by ExpertsThe correct answer is:
A
An antibiotic resistance gene in a vector acts as a selectable marker. It helps identify transformed cells—cells that have successfully taken up the recombinant DNA.
Transformed cells survive in the presence of antibiotic because they carry the resistance gene.
Non-transformed cells die.
