Recombinant DNA bearing ampicillin resistance gene is passed in E. coli. The latter are spread on agar plates containing ampicillin. Then

If a recombinant DNA bearing gene for ampicillin resistance is transferred into E. coli cells and the host cells are spread on agar plates containing amplicillin, then:

If a recombinant DNA bearing gene for ampicillin resistance if transferred into E.Coli cells and the host cells are spread on agar plates containing ampicillin, then:

If a re combinant DNA bearing ge ne for tetracyclin resistance is transferred into E.coli cells and the host cells are spread on agar plates containing tetracyclin then :-

Assertion: The ampicillin resistance gene is called as selectable marker gene Reason :If host cells are spreaded on agar plates contraining ampicillin and only untransformed cells will survive

What does the ampicillin-resistant gene act as ?

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

If a recombinant DNA bearing gene for resistance to antibiotic ampicillin is transferred to E.coli cells, the host cells become transformed into ampicillin resistant cells. If such bacteria are transferred on agar plates containing ampicillin, only transformants will grown and the untransformed recipient cells will die. The ampicillin resistant gene in this case is called as 1) selectable marker 2) recombinant protein 3) cloning site 4) chemical scalpels
