If a recombinant DNA bearing gene for resistance to antibiotic ampicillin is transferred to E.coli cells, host cells become transformed into ampicillin-resistant cells. If such bacteria are transferred on agar plates containing ampicillin, only transformants will grow and non-transformed recipient cells will die. The ampicillin-resistant gene in this case is called as _______________.
