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

Assertion : Selectrable markers helps in identifying and eliminating non-transformants and selectively permitting the growth of transformants Reason: If a recombinant DNA bearing gene for resistance to ampicillin is transferred into E.coli cells, the host cells become transformed into ampicillin-resistant cells

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

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

(a) Explain how to find whether an E. coli bacterium has transformed or not when a recombinant DNA bearing ampicillin resistant gene is transferred into it. (b) What does the ampicillin resistant gene act as in the above case?
